INTRODUCTION. 

The  present  essay  describes  in  detail  iind  discusses  the  classifi- 
cation of  a  group  of  grasshoppers  which  forms  the  prevailing  type  of 
orthopteran  life  throughout  North  America — the  common  short-horned. 
grassho])i)ers  one  sees  every  summer  day.  Its  best  known  representa- 
tive to  the  world  at  large  is  the  destructive  migratory  locust  of  the 
West,  the  so  called  '*  Kocky  ^Mountain  Locust."'  The  outbreak  of  this 
insect  has  been  at  times  extremely  disastrous;  so  much  so  that  a  Gov- 
ernment commission  was  for  several  years  iu  existence,  which  pub- 
lished nearly  twenty  years  ago  two  voluminous  reports  in  which  it  and 
one  or  two  of  its  immediate  allies  were  studie«l  with  a  minuteness  and 
thoroughness,  and  illustrated  with  a  fullness  very  rarely  given  to  any 
surh  insignificant  looking  creature. 

This  destructive  insect  has  nniijerous  closely  related  allies  in  all  parts 
of  the  United  States,  many  of  which  often  abound  to  such  an  extent  as 
to  do  serious  damage  to  crops,  and  a  few  of  them  have  been  known  to 
migrate  in  similar  fashion  (though  over  a  far  more  restricted  area),  so 
that  they  have  sometimes  been  mistaken  by  the  uninstructed  for  that 
destructive  pest. 

The  grt)up  is  almost  confined  to  North  America,  and  a  great  many 
species  hiive  been  described  by  various  writers  in  a  more  or  less  <lesul- 
toiy  manner.  It  is  the  aim  of  the  present  i)aper  to  enlarge  and  sys- 
tematize our  knowledge  of  this  important  group  as  a  basis  for  future 
studies.  No  group  of  North  Americaii  Orthoi)tera  has  been  in  greater 
need  of  revision.

"Melaiiopli  are  Acri<lijiiis  in  which  the  antennae  are  hinder  than  the  fore 
femora,  whieli  liave  no  tbveohie  ou  the  vertex,  the  tsiHti^iinn  ii.ore  or  less 
<letlexed,  passing  insensibly  into  the  frontal  eosta,  the  prosternuni 
nineronate,  no  sharp  and  distinct  lateral  caritiae  (or  they  are  rarely 
jjresent),  an  aroliuin  on  all  the  tarsi,  the  hind  tibiae  with  smooth  mar 
gins,  i»rovided  with  9-14  (by  rare  exception  8)  spines  regularly  disposeii 
in  the  outer  series,  whi<'h  lacks  an  ai)ical  representative,  an<l  the  second 
liind  tarsal  joint  only  half  as  long  as  the  first. 

.  To  state  their  characters  more  in  detail,  the  Melanopli  maybe  described 
as  Acridians,  generally  of  small  or  medium  size,  never  very  large,  iu 
which  the  head  is  not  greatly  exserted  and  the  face  is  ujoderately  obli(pie 
or  subvertical ;  the  antennae  are  linear,  longer  than  the  fore  femora;  the 
eyes  are  of  moderate  size,  not  very  strongly  ]>rominent,  never  twice  as 
long  as  the  intraocular  portion  of  the  genae,  the  interspace  between 
them  very  rarely  broad,  generally  narrow ;  the  fastigium  is  more  or  less 
declivent,  never  greatly  i)roduced  in  the  axis  of  the  body,  apically  entire 
and  with  no  transverse  ruga,  passing  insensibly  and  with  obtuse  arcu- 
ation  into  the  frontal  costa;  the  latter  is  hardly  rounded  as  seen  from 
the  side,  percurrent  or  subpercurrent,  generally  sulcate,  the  sulcation 
ordinarily  confined  to  the  lower  portion:  without  foveolae, the  tempora 
small,  obliquely  declivent,  confused  with  the  front;  the  superior  ocelli 
more  distant  than  the  antennal  scrobes;  the  lateral  carinae  of  the  face 
nearly  equidistant  from  the  lateral  margins  of  the  frontal  costa,  but 
slightly  divergent  inferiorly.  The  dorsum  ot  the  pronotum  is  nearly 
plane  and  without  a  crest,  generally  with  no  distinct  lateral  carinae,  but 
at  most  with  rounded  shoulders  or  feeble  rugae  to  represent  them,  but 
often  passing  insensibly  into  the  lateral  lobes;  the  principal  sulcus  is 
continuous;  the  prozona  is  generally  smooth  or  obsoletely  i)unctate, 
never  tuberculate,  its  sulci  generally  feebly  impressed,  often  mesialiy 
interrui)ted  or  subinterrui)ted,  the  i)osterior  sulcus  often  distinctly 
divergent  laterally  from  the  principal  suh'us;  the  metazona  is  generally 
shorter  than  the  prozona  and  lies  iu  the  same  or  nearly  the  same  plane 
with  it,  almost  always  densely  punctate;  the  lateral  lobes  are  truncate 
or  subtruncate  posteriorly,  with  no  humeral  sinus  or  only  a  feeble  one. 
the  posterior  lower  angle  distinctly  obtuse.  The  prosternum  is  armed 
with  a  spine  which  is  usually  rather  prominent  and  conical,  sometimes 
truncate,  never  sinuate,  generally  vertical  on  the  posterior  face,  nearly 
or  quite  as  high  as  the  anterior  coxae,  the  posterior  portion  of  the  pro 
sternum  not  or  but  slightly  tumescent;  the  roesosternal  lobes  are  quad- 
rate or  transverse,  separated  more  or  less  widely,  the  apical  inner  angle 
rectangulate  or  obtusangulate,  generally  rounded  Coften  obtusely),  tie 
inner  margins  generally  rounded,  often  posteriorly  divergent;  the  meta 
sternal  lobes  are  contiguous  or  not  very  distant  excepting  sometimes 
in  the  female  and  then  rarely  as  distant  or  even  nearly  as  distant  as

either  side  of  an  intorealary  vein;  the  win^^s  are  almost  always  elear 
and  uniform,  never  detinitidy  i)ictured,  the  veins  never  sealariform,  the 
ill eolae  (|uadrate  or  lon«(er  than  bnnid.  All  the  tarsi  are  furnished  with 
ail  aroliiiin,  the  front  legs  are  less  distantly  separated  than  the  hind 
p;iir,  the  fore  tarsi  are  of  moderate  lentfth,the  tirst  joint  short  or  rather 
sliort:  tiie  hind  femora  are  distinctly  iiierassute  basally,  ;i:enerally  sur- 
piiss  the  abdomen,  the  upper  face  fjenerally  smooth,  the  dorsal  carina 
eiitin',  unarmed,  not  profoundly  excised  befoie  the  jjeniculation;  the 
bind  tibiae  have  smooth  lateral  marfflns,  the  spines  of  the  outer  and 
inner  <«Mie8  are  equal  or  subequal  in  length,  those  of  the  outer  series 
typically  nine'  or  more  in  number,  rarely  exceeding  fourteen,  ])laced  at 
subequal  distances  apart  and  lacking  an  apical  spine  next  the  calcaria; 
the  hind  tibiae  have  the  lirst  Joint  not  compressed,  equal  to  or  slightly 
longer  than  the  third,  the  second  much  shorter,  generally  a  half  shorter, 
than  the  tirst  as  seen  from  above.  The  second  dorsal  segment  of  the 
abdomen  is  neither  granulate  nor  dentate  at  the  anterior  angles,  the 
extremity  of  the  abdomen  in  the  male  generally  more  or  less  clavate 
and  recurved,  the  supraanal  i)late  not  tuberculate,  with  a  basal  median 
sulcus,  a  furcula  usually  present,  the  cerci  very  variable,  rarely  longer 
than  the  supraanal  plate,  straight  or  gently  curved,  never  abruptly 
recurved  basally,  generally  compressed  at  least  in  part,  often  laminate^ 
but  with  no  indireeted  median  spine. 

The  foundation  for  our  present  knowledge  of  the  structural  features 
of  the  Melanopli  was  laid  by  StiU  ^  and  enlarged  in  his  Systema 
Acrideodeoruin  (1S78)  and  his  Observations  Orthopterologiques,  II£ 
(1878).  In  its  present  form  the  groui)  was  first  detined  and  named  by 
Brunner  von  Wattenwyl,^  who  applied  to  it  the  terra  Tezotettiges. 
I  have  here  limited  it  strictly  in  the  same  manner,  but  it  will  appear 
that  it  contains  a  very  much  larger  number  ot  generic  types  than  were 
credited  to  it  by  Brunner  and  a  vast  multitude  of  species.  I  shall 
moreover  show  below,  when  treating  the  genus  Podisma,*  that  the  gen- 
eric term  Pezotettix,  from  which  Brunner  derived  the  name  of  the 
group,  has  been  misapplied  of  recent  years,  and  should  be  referred  to 
the  group  called  Platyphymata  in  Brunner's  Bevision.  I  have  accord- 
ingly here  named  the  present  group  Melanopli  after  its  predominant 
genus  }felanoplus,  the  species  of  which  far  outnumber  all  the  others  com- 
,  bined.    Giglio  Tos  in  recent  papers  has  described  several  new  genera  and 

I  '  By  exception,  in  one  sex  or  on  one  side  of  the  body,  there  may  be  only  eight.

ab(»ut  twenty  known   species  mostly  referred  to  PichmpluH,  besides 
ruruilichrtr  '.uH^  with  four  species  in  l*aragruay.     The  remaininj;^  genera 
are   exi'lusively    North    American,    but    eleven   of    them — X(tnt,s(>nH(.

species,  besides  two  species  of  the  8(»uth  American  genus  Paradivhro 
plus,  are  found  exclusively  in  Central  America  and  Mexico,  or  only  i)a8s 
the  borders  of  the  United  States  narrowly. 

All  of  these  Central  and  South  American  genera  (with  the  single 
exception  of  /V<t7o(7ro/<)  belong  to  the  division  of  Melanojdi  in  which 
the  lateral  margins  of  the  subgenital  plate  of  the  male  are  not  at  all 
anji>liateatthebase;  and  they  comprise  all  but  three  of  the  genera  belong 
ing  to  that  section,  these  three  being  GymnoficirtHes  with  <me  species  in 
Florida,  1 1 ypovhlora  with  one  species  from  the  Canadian  border  to  Kansas 
and  Colorado,  and  VumpiiUunntha  with  four  species,  three  ranging 
from  ^Nebraska  to  Texas  and  one  fouiul  in  Mexico.  The  great  bulk  of 
the  species  and  most  of  the  genera  (including  all  but  one — PhUockon — 
of  those  belonging  in  the  section  with  ami)liate  basal  margins  to  the 
subgenital  idate)  are  contined  to  the  United  States  and  Cauada,  where 
they  form  one  of  the  dominant  types  of  Acridiidae. 

This  division,  that  with  ampliate  basal  margins,  is  represented  (apart 
from  Fhiloclcon  with  its  single  species)  by  fourteen  genera  and  one  hun- 
dred and  seventy-nine  species,  of  which  only  four  genera  occur  south 
of  our  border,  with  thirteen  species  confined  to  Mexico,  and  twelve 
others  found  both  in  Mexico  and  the  United  States;  leaving  ten  genera 
wholly,  and  four  others  abnost  wholly,  belonging  to  the  more  northern  i 
region,  with  one  hundred  and  sixty-six  species.  No  species  of  either  j 
division  are  found  in  tlie  Antilles. 

With  tritling  exceptions,  then,  the  division  with  nonampliate  basal 
margins  to  the  subgenital  plate  is  characteristic  of  Central  and  South 
America— or  subtropical  and  tropical  America — while  the  other  divi 
sion.  vastly  more   important,  is  characteristically   temperate    North 
American,  with  oneoutlier  intemperate  Europe  Asia. 

The  dominant  genus  is  Melanoplus  with  one  hundred  and  thirty  one 
species  described  in  the  present  paper;  a  number  more  are  known  to

of  them  are  nionotypie. 

The  ;;enera  with  widest  latitudinal  ran;;e  (over  twenty  decrees)  are, 
primarily,  Mehniopliix,  and  then  lltHptrntetti.v  (eipht  speeies),  Phiw-

follows  hard  after.  The  jjenera  characteristics  of  the  I'nited  States, 
with  narrowest  known  limits,  are  (hfrnnitsrirtftcs  and  Eotvttii\  both 
known  only  from  Florida.  These  last  tw(»,  with  rarojifa  an<l  .[pt*no-

to  the  eastern  I'nited  States,  if  Texas  may  be  included  in  that  term, 
for  they  do  not  extend  west  of  that.  Most  of  the  ji:enera  are  western,

a<*ross  the  continent,  or  at  all  events  on  opposite  sides  of  the  continent, 
ar<'  Mrlauoplus,  Ilcsperotcftij',  and  Podismo.  Acolophta  (ten  species), 
Jinnh/notcH  (seven  species),  PoccUoUttir  (three  species),  OednleonotuH 
(one  species),  and  Ancnfophts  (one  species)  are  characteristic  of  the 
extreme  West.  Finally,  Ihipovhlorn  (one  species),  Bradipiotes  (seven 
fi}»ecies),  Podisma  (ei<;ht  si)ecies),  and  Asemoplnx  (one  species)  are  con- 
fined or  nearly  (routined  t(»  the  rejjion  north  of  latitude  3.~>^.  Podlnma

bution (d'  Mel(nin2)his,  with  its  great  prej)onderance  of  forms,  further 
details  will  be  jiiven  under  that  genus. 

There  are  but  few  species  which  range  across  the  continent,  yet  not 
a  few  have  a  very  wide  distribution.  The  examples  of  the  former  are 
wholly  contiiied  *o  Melanoplus:  M.  Gthuiis,  fa-sciatus,  fcnnir-ntbrum, 
eatremHs^viinor.nud/emoratas,  }f.  ertrcmus only  in  the  high  north.  As 
illustrations  of  the  latter  may  be  mentioned  Hespcrotctti.v  pratensis^ 
Fhoetaliotes  nehrascensis,  Paroxyn  iioridann,  OedaleonotuH  enic/ma,  and 
the  following  species  of  Mehtnoplus :  fiabcUi/er,  spreiun,  Hciidderi^dmr- 
son',,  cinereus,  Packard  a,  luridus,  difrrentialis,  biviftatnx,  and  pnnctnla- 
tu8.  Most  of  these  range  more  widely  from  north  to  south  than  from 
east  to  west.  About  three  fourths  of  all  the  species  are  known  from 
west  of  the  Mississippi  River  only. 

Dimorphism  in  lenfjth  of  tegmina. — We  find  in  the  Melanopli  every 
variation  possible  in  the  length  of  the  tegmina,  but  the  species  are  in 
general  tolerably  well  tixed  in  this  respect.  The  same  is  the  case  with 
most  of  the  gener; .  the  species  of  which  are  in  each  case  generally

same  jnfenus  obtains  in  the  two  largest  genera:  Melanoplus.  where  the 
speiies  may  range  from  those  with  merely  lateral  pads  to  those  with 
tcgmina  far  surpassing  the  hind  femora;  and  Podisma.  where  they 
range  from  apterous  species  to  those  with  tegmina  lialf  as  long  as  the 
abdomen,  lint  tiiis  range  is  not  confined  to  the  larger  g«*nera,  for  sev- 
eral monotypic  geuera  {Dernlrotettir,  PhoctnUotcH.  and  Ocdaleonotun)  dis- 
play a  wide  difference  between  different  forms  of  the  single  si)ecies  they 
])ossess,  in  the  length  of  the  tegmina,  a  differeiu-e  which  is  also  paral 
leled  or  almost  i)aralleled  .iinong  certain  species  of  the  genera  Hespero- 
tetfi.v,  roili-smaj  Melanojjiusj  and  I'aroxya^  and  particularly  of  the  genus 
Mclainqilns. 

This  last  genus  is  of  particular  interest  in  this  connection,  for  it  is 
subefjually  divided  between  distinctly  short  winged  and  distinctly  long 
winged  forms,  which  only  rarely  Ji])pear  to  be  closely  allied;  yet  in  four 
of  tlie  species,  .1/,  dmcaoni^  M.  margiuatHs^  M.fami<itus.i'd\\(!i  M.e.rtremus^r- 
si)ecies  in  no  way  closely  related — there  is  a  marked  dimorphism  in 
respect  of  the  length  of  the  tegmina,  the  first  two  being  normally  pos- 
sessed of  tegmina  only  slightly  longer  than  the  pronotum,  the  last  two 
of  tegmina  hardly  as  long,  if  as  lorf^,  as  the  abdomen,  but  all  occasion- 
ally e([uipped  with  tegmina  distinctly  surpassing  the  hind  femora. 
When, however,  we  compare  these  fully  developed  tegmina  (Plate  I,  figs. 
«,  c,  /,  i)  either  with  the  abbreviated  tegmina  of  the  same  species,  as  in 
Jf.  extremns  (Plate  I,  fig.  //),  or  with  those  of  their  nearest  macropterous 
allies,  .]/.  (/lafhtoni  (Plate  I,  fig.  h),  M.paroxyoides  (Plate  I,  fig.  ^),and 
M.  horealis  (Plate  I,  fig.  ^7),  as  in  the  other  species,  we  can  not  fail  to  be 
struck  by  the  common  differences  which  separate  these  abnormal  macrop- 
terous tegmina  from  the  normal  tegmina  of  the  genus.  (See  further  the 
tegmina  of  the  type  of  the  genus,  M.  femurruhrum,  Plate  I,  fig.  //.). 
Instead  of  the  regularly  tapering  form  normal  to  the  genus,  the  added 
portion,  which  is  largely  the  extension  of  the  region  beyond  the  post- 
radial  intercalary  area,  is  nearly  equal,  giving  the  tegmina  a  consider- 
ably greater  apical  breadth  and  a  consequent  openness  of  neuration, 
besides  a  less  ta|)ering  form.  What  is  further  to  be  noticed  is  that  this 
apical  breadth  and  openness  of  neuration  is  also  the  characteristic  of 
several  cases  in  other  genera  where  there  is  similar  dimorphism  in  length 
of  tegmina,  as  in  Dendroiettix  querc.ns^  Podhma  alpiniu  and  Phoetaliotes 
nehrascensis  (Plate  I,  fig.  e).  In  Podismn  the  most  abbreviated  form  ot 
wing  is  plainly  normal,  and  I  am  therefore  inclined  from  these  examples 
to  regard  the  abbreviated  as  the  normal  form  in  Dendrotettix,  Phoeta 
UoteSj^wd  the  species  of  Mela)ioplufi  (except,  of  course,  M.  femur  rubrum 
here  illustrated.  The  same,  however,  is  not  the  case  in  Oedaleonotua, 
where  dimorphism  of  similar  degree  is  found,  and  it  is  therefore  prob

able  that  the  fully  eqiiijiped  form  is  here  the  normal,  although,  so  far  as 
we  now  know,  it  is  nuieh  less  eommonly  found  tlian  the  braehy])tei'ous 
forms.  Other  instances  where  there  is  considerable  but  not  so  marked 
nor  ijerhaps  so  uniform  a  difference  in  wing  length  is  in  Varoxya  Jiori- 
dnnu  and  jjcrhaps  HeHperofettix  riridis^  in  both  which  genera  the  length 
(►f  the  tegniinais  variable.  In  these  two  species  the  tegmina  are  not 
sipically  broad  in  the  macropterous  forms,  and  differ  only  in  length  from 
the  brachypteroas  forms. 

Materials,  etc. — The  si)ecimens  forming  the  basis  of  the  present  study 
ure  in  my  own  cabinet,  which  contains,  often  in  large  series,  the  greater 
portion  of  the  species,  collected  in  large  part  by  myself  in  different 
sections  of  the  country,  but  supplemented  by  specimens  secured  from 
the  Texan  collections  of  Boll  and  Belfrage,  a  large  series  from  Iowa 
and  Illinois  obtained  by  Doc  _ir  J.  A.  Allen,  and  others  from  the  S<uith- 
western  States  and  Mexico  by  Edward  Palmer;  besides  the  entire  col- 
lection of  Mr.  P.  R.  Uhler,  who  many  years  ago  generously  turne<l  over 
to  me  his  own  private  collection,  containing  among  other  things  many 
8})ecimens  obtained  from  the  early  exi)lorers  of  the  West. 

Through  the  favor  of  the  Assistant  Secretary  of  the  Smithsonian 
Institution,  in  charge  of  the  United  States  National  ^Museum,  Doctor  (f. 
Brown  (ioode,  and  the  Honorary  Curator  of  Insects  in  the  same  insti- 
tution, Doctor  C.  V.  liiley,  I  have  had  the  Museum's  entire  collection  of 
Melnnopli  in  my  hands  during  this  study.  The  collections  of  the 
Museum  of  Comparative  Zoology  in  Cambridge,  Massachusetts,  have 
also  been  open  to  me.  My  neighbors  and  colleagues,  Mr.  Samuel  Hen- 
shaw  and  Mr.  A.  P.  Morse,  have  also  placed  all  their  Melanopli  in  my 
hands;  and  from  Professor  Lawrence  Bruner,  of  Lincoln,  Nebraska,  I 
have  received  a  complete  series  of  all  the  forms  known  to  him,  which  has 
been  on  the  whole  the  Liost  imimrtant  aid  I  have  received.  Professor 
Jerome  McNeill,  who  had  begun  a  study  of  the  Melanopli,  mainly  of  the 
National  Museum,not  only  generously  transferred  the  work  to  my  hands, 
but  gave  me  free  use  of  his  notes  and  sent  me  several  species  otherwise 
unknown  to  me.  The  University  of  Kansas  sent  me  a  series  of  interest- 
ing western  forms  in  its  museum,  Mr.  W.  S.  Blatchley  a  series  of  the 
Indiana  species  known  to  him.  Professor  C.  P.  Gillette  interesting  forms 
from  Colorado,  and  Professor  II.  E.  Weed  a  few  from  Mississippi.  All 
of  these  gentlemen  have  freely  answered  many  inquiries  made  of  Vuem, 
and  any  failing  in  the  present  paper  must  be  laid  at  my  dod.  In  this 
way  I  have  seen  the  tj  pes  of  nearly  all  the  species  described  from 
North  Ameri(  a,  and  while  in  England  Mr.  Samuel  Henshaw  kindly 
examined  for  me  several  of  Walker's  types  at  the  British  Museum.  I 
have  been  further  aided  for  the  European  species  by  Ilofrath  Brunner 
von  Wattenwyl,  Doctor  Chr.  Aurivillius,  and  Mons.  A.  de  Bormans. 

In  all,  I  have  examined  for  the  purposes  of  this  paper  nearly  eight 
tliousand  specimens,  of  which  about  seven  thousand   belong  to  the

single  genus  MilanopluH.  The  sexes  are  nearly  equally  divided,  tho 
males  forming  about  forty-six  per  cent  of  the  whole.  Thirty  genera 
(eighteen  new)  and  two  hundred  and  seven  species  (one  hundred  and 
fifteen  new)  are  described  in  the  present  paper. 

Finally,  by  the  aid  of  a  grant  from  the  Elizabeth  Thompson  Soi 
ENCE  Fund  I  have  been  able  to  procure  illustrations  of  the  abdominal 
apiHMidages  of  every  avaiable  species. 

A  few  words  should  be  added  regarding  certain  details  of  presenta 
tion:  Instead  of  giving  the  range  of  variation  in  the  measurements  of 
each  species,  I  have  selected  as  far  as  possible  tyi)ical  average  speci 
mens,  male  and  female,  for  the  purpose,  taking  the  measurements  of  all 
parts  from  the  same  individuals.  The  number  of  individuals  of  each 
species  seen  is  given,  and  the  localities  from  which  they  came  immedi- 
ately added,  with  the  name  of  the  collector  (when  not  myself),  and 
when  not  from  my  own  collection,  the  source  from  which  I  have  received 
them  stated  (in  parentheses);  occasionally  my  own  name  is  there 
added,  when  specimens  from  the  same  source  are  also  found  in  my  col- 
lection ;  where  no  parenthesis  follows  the  locality,  the  specimens  referred 
to  are  in  my  collection. 

In  describing  the  abdominal  appendages  of  the  males,  I  have  found 
it  convenient  to  introduce  a  few  new  terms.  These  are:  Furcida  for 
the  i)air  of  backward  directed  apophyses  of  the  last  dorsal  segment, 
which  overlie,  generally  in  a  more  or  less  forked  position,  the  base  ot 
the  supraanal  plate;  infracercal  plates  for  the  variously  developed  but 
generally  inconspicuous  paired  plates,  which  underlie  in  part  the  cerci, 
in  i)art  the  lateral  portions  of  the  supraanal  plate;  and  pallium  for  the 
sometimes  erectile,  membranous  pellicle  partially  closing  the  open 
cavity  formed  of  the  walls  of  the  subgenital  i)late,  and  variously  devel 
oped  in  the  ditterent  genera.       ,   :^    ^  ;  ;     '

in  the  species  of  the  alternate  category  (J-  ft')  the  cerci  are  very  slender  and  tapering. 

"■In  numy  cases  the  interspace  is  truncato-cuneiform  or  broadly  clepaydral,  in 
wliich  cases  the  breadth  is  to  be  measured  in  the  middle.  In  a  single  species  of 
Podisma,  P.  dairisama,  tbe  interspace  is  slightly  longitudinal.

This  gen.is  is  very  distinct  from  anything  known  to  nie,  and  I  have

nic  ^hat  he  has  an  immature  male  with  nluo  f:  'mCS,  which  agrees  with

Three  males,  2  females.  Mount  Orizaba,  Mexico, W.  S.  Blatchley;  the 
saine,  11,500  feet,  March  (L.  Bruner).  Originally  described  from  tht 
same  mountain  as  collected  by  M.  Aug.  Salic  "au  pied  de  la  niegc." 
Mr.  Ulatchley  informs  me  that  at  the  time  of  his  visit  the  snow  line 
was  at  15,000  feet,  and  adds  that  he  took  a  single  specimen  of  the  specie^ 
at  13,500  feet,  "a  very  few  individuals  may  have  been  taken  as  low  as 
9,000  feet,  but  the  species  was  common  only  between  10,000  feet  and 
12,000  feet;  above  12,000  feet  scarce." 

According  to  statements  in  the  daily  press,^  Orizaba,  which  is  o 
volcanic  origin,  showed  signs  of  a  ^"  lewal  of  activity  early  in  Marcli. 
1895,  when  hot  ashes  were  ejected,  the  snow  disai)])eared  from  the  sum 
mit  and  the  vegetation  of  the  ui»per  part  of  the  mountain  was  buriHii 
Possibly  this  means  the  extinction  of  Paradichroplus  mexicanus. 

The  following  description  of  the  living  insect,  made  upon  the  sjtot.

ttie  space  between  the  eyes,  ec^ual,  percurrent,  sulcate;  antennae  only 
a  little  longer  than  head  and  i)ronotum  together.  I'ronotum  truncate  at 
each  extremity,  barely  broader  behind  than  in  front,  transversely 
obnvex,the  disk  ])assing  insensibly  into  the  vertical  lateral  lobes,  a  slight 
median  carina;  i)r()zona  transverse,  slightly  less  than  twice  as  long  as 
the  metazona,  divided  in  the  middle  by  a  distinct  transverse  sulcus, 
followed  at  a  short  distance  behind  by  a  less  distinct  sinuous  sulcus,

The  antennae  of  the  nnUe  are  scarcely  so  long  in  this  species  as  in 
tlic  others;  it  differs  decidedly  from  E.  concinnm  in  the  bent  and  narrow 
cerci  as  well  as  in  the  more  nearly  quadrate  interspace  between  the 
mesostprnal  lobes  of  the  male;  from  A*,  pihsm,  to  which  It  seems  more 
nearly  allied  and  for  which  1  at  first  mistook  it,  it  differs  in  the  cerci  of 
the  male,  which  do  not  narrow  before  the  n.iddle,  in  being  a  smaller 
iiibcct,  besides  having  a  duller  coloring  with  more  contrasted  markings, 
to  judge  from  JStul's  description.

I  iiave  not  see",  this  species,  and  acco'-dingly  give  SttlFs  description, 
englished.  The  descripiion  is  mainly  a  comjjarative  one,  the  basis  of 
comi)ari8()n  being  Aidemona  azteca,  next  which  Stal  jdaced  it,  in  the 
same  section  of  Pezotettix. 

Olivaceous;  legs  yellowi.sh  olivaceous ;  hind  tibiae  greenish  olivaceous, 
the  base  and  geuiculation  proper  of  the  hind  femora  black;  tegmiua 
rudimentary.     Length  of  male  10  mm. 

J/^f/t'.— Inters  J,  \ce  between  mesosternal  lobes  a  little  longer  than 
broad,  ^ith  parallel  sides,  much  narrower  than  the  lobes  themselves; 
metasteinal  lobes  subcont^  ^uous;  eyes  large,  rather  convex;  apical 
margin  [of  the  i>ronotumJ  gradually  and  obtusely  sinuate,  slightly 
emarginate  in  the  middle,  destitute  of  a  lobe;  supraanal  plate  fur- 
nished with  a  gradually  narrowing  sulcus,  extending  beyond  the 
middle  of  the  plate;  cerci  gently  curved,  compressed  and  rather  broad 
throughout,  before  the  middle  slightly  narrowed;  subgenital  plate 
short,  very  strongly  recurved;  abdomen  posteriorly  tumescent  and 
somewhat  recurved. 

Distinguished  from  Aidemona  azieca  by  the  front  and  prozona  less 

tnsely  punctate,  frontal  costa  obtusely  subsulcate,  narrower  between 
e  antennae,  the  sides  parallel  but  slightly  narrowed  at  the  base,  the 
i|terspace  between  the  eyes  narrower,   the  disk  of   the  pronotum 
looth,  abbreviate  and  truncate  anteriorly,  the  metazona  about  half 
long  as  the  prozona,  tegmma  rudimentary,  widely  separated,  ellip-

with  no  obtuse  apically  eraargfinate  lobe  [furcnla],  the  hind  femora 
slenderer  and  longer,  i)rosternal  si>ine  conical,  and  the  antennae  longei-, 
more  than  half  as  long  as  the   body;  hind  tibiae  in  the  specinicii 
described  furnished  exteriorly  with  eight  black  spines,  greenish  oliva 
ceous  at  the  base. 

A  female  specimen,  in  which  the  dorsum  of  the  body  and  of  the  hind 
femora  are  ferruginous,  with  sn)alh?r  eyes,  the  interspace  between  tlie 
mesostemal  lobes  subtransverse  and  scarcely  narrower  than  the  lobes 
themselvts,  and  metasternal  lobes  moderately  distant,  is  very  i)robabIy 
to  be  referred  to  the  species  described  above.  In  this  specimen  the 
antennae  are  mutilated  and  the  hind  tibiae  armed  exteriorly  with  nine 
spines. 

Mexico  (Brunner's  collection). 

To  this  I  may  add  that  the  i)resent  species  is  certainly  very  close  to 
the  others  described  above  under  this  genus,  but  seems  to  be  slightly 
larger  than  either,  and  to  ditfer  by  the  cerci  of  the  male  to  a  greater 
degree  than  either  of  these  do  from  each  other.  It  is  evidently  also  of 
a  lighter  color,  and  no  mention  is  made  by  Stal  of  a  very  distinct  dark 
lateral  band,  which  is  characteristic  cf  the  other  two.

It  is  possible  that  the  nmle,  which  comes  from  Venis  Mecas,  may  be 
distinct  from  the  females,  which  come  from  all  the  localities;  in  that 
case  the  name  should  be  retained  for  the  male  as  the  most  characteristic

the  i)osterior  half,  the  front  and  hind  margins  truncate,  the  latter  some- 
times almost  impercejitibly  emarj^inate  in  the  middle,  especially  in  th(5

subriijioso-punctate  throughout,  unless  it  be  that  the  disk  is  coarser 
than  the  detiected  lobes;  nieso-  and  metanota,  and  the  basal  segments 
of  the  abdomen  similarly  but  more  obscurely  punctured.  The  general 
color  is  a  greenish  yellow  more  or  less  tinged  with  brown,  brighter  in  the 
male  than  in  the  female,  and  marked  with  blackish  fuscous;  the  darker 
markings  consist,  i)rincii)ally,  of  a  dorsal  stripe,  which  either  extends 
over  the  pronotum  as  a  broad  equal  band,  often  fainter  in  the  middle, 
with  a  triangular  extension  on  the  head,  and  sometimes  a  narrowiiij,' 
iufuscation  on  the  meso-  and  metanota  (male),  or  forms  an  obovate

another  by  a  yellowish  median  line  (female) ;  also  of  a  broad  lateral  band, 
which  extends  from  behind  the  eye  backward,  either  to  the  hinder  edj,'e 
of  the  prothorax,  its  upper  margin  straight,  its  lower  arcuate  (male),  or 
across  the  prozona  only,  occasionally  in  an  obscure  manner  across  tlie 
metazoua  also,  both  margins  arcuate  (female);  beyond  this  the  latera 
band  extends  over  the  remainder  of  the  thorax  and  over  the  abdomen, 
often  broken  into  spots  on  the  latter,  and  always  enlivened  on  the  for- 
mer by  anoblifjue  yellowish  line,  which  crosses  it  on  the  metathoracic 
episterna.  The  face  partakes  of  the  color  of  the  under  surface,  as  do  tlie 
bases  of  the  antennae;  beyond,  the  antennae  become  slightly  rufous 
just  behind  its  narrowest  point  the  vertex  has  a  transverse  blackish

2.  PARAIDEMONA  MIMICA,  new  species. 

(Phite  III,  ti«.  10.) 

Yellowish  testaceous,  heavily  banded  with  black,  especially  on  the 
sides,  and  more  markedly  in  the  male  than  the  female.  Head  with 
the  intersi)ace  between  the  eyes  very  narrow,  especially  in  the  male, 
the  fastigium  between  them  sulcate,  narrowly  in  the  m'lle,  the  sulcation 
continuing  so  as  to  be  subcoutinuous  with  that  of  the  frontal  costa, 
wliich  is  sulcate  in  its  whole  extent,  equal,  and  broader  than  the  inter- 
space between  the  eyes,  rronotum  punctate  as  in  P.  punvtata,  and  as 
there  a  glabrous  spot  free  of  punctuation  occurs  on  the  prozona  at  the 
summit  of  the  lateral  lobes.  A  black  stripe,  sometimes  wanting  or 
feebly  fuscous  in  the  female,  begins  at  some  point  on  the  fastigium  and 
continues  backward,  broadening  on  the  head  so  as  to  include  nearly 
the  entire  vertex,  and  crosses  the  pronotum  as  a  broad  mediodoisal 
band,  as  broad  as  the  length  of  the  metazona,  or  in  the  female  even 
broader;  it  is  sometimes  obscure  or  wholly  obsolete  in  the  female,  while 
in  the  male  it  is  always  distinct,  at  least  on  the  prozona,  and  generally 
continues,  though  narrowed,  over  the  meso-  and  metanota.  The  lat- 
eral band,  generally  rufo-piceous,  is  still  broader  and  is  sharply  defined 
above  and  below,  often  uninterrupted  on  the  metazona  in  the  female, 
where  it  widens  so  as  to  include  behind  the  whole  of  the  thoracic  pleura 
(excepting  the  episterna)  and  the  sides  of  the  first  four  abdominal  seg- 
ments; above  it  is  more  or  less  distinctly  accompanied  in  the  female  by 
a  testaceous  stripe.  The  dorsum  of  the  abdomen  of  the  female  lacks 
the  double  series  of  oblique  lateral  dashes  found  in  P.  punctata^  or  has 
tliem  very  feebly  marked.  Hind  femora  yellowish  testaceous,  the  outer 
face  growing  darker  below,  giving  there  a  broken  irregular  blackish 
stripe;  hind  tibiae  glaucous,  the  pallid  spines  black  tipped.    Supraanal

to  be  <listinguish(Ml  from  it,  except  by  the  abdominal  ap}>einlagesof  the 
male,  which  are  rennirkably  distinct.  Tiiere  is  no  sign  in  the  female  of 
tlie  dark  mediodorsal  fusiform  patch  on  the  pronotum.and  the  coloring 
of  the  female  in  both  species  is  very  variable.  • 

There  are  two  other  forms  of  Paraidennma  known  to  me,  which  I 
deem  probably  distinct  from  either  of  the  above,  but  being  known 
only  by  the  female,  i  only  allude  to  them.  Both  have  relatively  heavy 
hind  femora. 

One  is  almost  wholly  olivaceous,  the  abdominal  carina  marked  with 
yellow,  and  with  yellow  shades  upon  the  sides  of  the  dorsum  of  the 
thorax;  it  comes  from  Carrizo  Springs,  Texas  (U.S.N.M.). 

The  other  is  almost  wholly  yellowish  testaceous,  with  no  dorsal  stripe 
and  relatively  feeble  and  fleeting  lateral  stripes;  it  comes  from  Dallas, 
Texas  (U.S.N.M.),  and  Veuis  Mecas,  San  Luis  Potosi,  Mexico,  January

Body  slender,  compressed,  very  thinly  pilose.  Head  not  prominent, 
the  summit  gently  arched,  the  fastigiuni  descending  with  moderate 
rapidity,  the  face  retreating  considerably;  interspace  between  the  eyes 
broad,  the  fastigiuni  scarcely  sulcate,  the  frontal  costa  rather  narrow, 
not  nearly  so  broad  as  the  space  between  the  eyes,  sulcate,  percurreiit, 
and  subequal;  eyes  moderate  in  size,  not  very  prominent,  similar  in  the 
two  sexes,  about  half  as  long  again  as  broad,  and  distinctly  longer  than 
the  anterior  intraocular  portion  of  the  genae;  antennae  moderately 
stout,  somewhat  longer  (male)  or  a  little  shorter  (female)  than  the  head 
and  pronotum  together.  Pronotum  subequal,  even  in  the  female,  very 
feebly  and  gradually  enlarging  in  passing  backward,  with  a  distinct

beyond  the  inner  si<lc  of  the  apical  margin ;  furcula  consisting  of  a  pair 
of  slight,  rounded,  feebly  projecting  lobes. 

This  genus  is  closely  aUied  to  Hypoehhira^  but  is  composed  of  gener- 
ally stouter  forms,  in  which  the  antennae  are  longer,  the  pronotum  is 
Qsually  rugulose  rather  than  punctate,  and  the  males  of  which  have 
iioie  tumid  anterior  femora,  besides  the  ditferences  pointed  out  in  our 
;;»l)le  of  genera. 

r.  ((rKtipcn)tis  may  be  taken  as  the  type. 

The  genus  occurs  only  in  the  West,  where  it  ranges  east  of  the  Kocky 
MMiiiitains  from  Nebraska  to  Texas,  and  occurs  again  in  Duraugo, 
T'xico.  _  _     ..

(Plate  IV,  fig.  5.) 

Dark  bluish  f^reen,  more  or  less  infuseated  and  enlivened  by  various 
shades  of  green.  A  broad,  longitudinal,  sordid  yeHow  stripe  behind  the 
ui)per  half  of  the  eyes,  beginning  at  their  nearest  approximation,  leaves 
on  the  top  of  the  head  a  broad,  ecjual,  dark  bluish  green  dorsal  stripe: 
the  genae  are  more  or  less  mottled  with  olivaceous  and  the  antennae  are 
ferruginous,  deeply  infuscated.  Pronotuin  more  or  less  deeply  tinged 
with  dark  olivaceous,  the  upper  half  of  the  lateral  lobes  of  the  prozona 
alone  pure  bluish  green,  though  the  dorsum  of  the  nietazona  approaches 
it.  Tegmina  dull  green,  infuscated  basally,  nearly  or  quite  half  as  long 
as  the  abdomen,  subacuminate.  Fore  and  middle  femora  dull  ferru- 
ginous, apically  dark  olivaceous;  hind  femora  stouter  than  in  the  two 
preceding  species,  bluish  green  on  the  outer  face,  slightly  infuscated  at 
the  incisures,  greenish  fuscous  above  feebly  bifasciate  with  fuscous, 
^avo-luteous  below  and  within,  and  with  a  feeble  and  broken  testa- 
ceous pregenicular  aiinulus;  hind  tibiae  pale  bluish  green,  deepest  at 
base,  followed  by  a  dull  luteous  annulus  and  becoming  lutescent  api 
cally,  the  spines  tipped  with  black.  8upraaiial  plate  of  male  similar  to 
that  of  the  two  preceding  species,  but  Hatter,  with  lower  ridges;  furcula 
as  there;  cerci  almost  as  long  as  the  supraanal  plate,  tapering  very 
rapidly  in  the  basal  third,  beyond  slender,  less  than  halt  as  broad  as 
the  base,  subequal,  expanding  feebly  beyond  the  middle  and  then 
tapering  again,  the  lower  portion  of  the  tip  very  slightly  produced  and 
very  feebly  curved  downward ;  infracercal  idates  much  as  in  the  preced- 
ing species  or  perhaps  broader  basally. 

Length  of  body,  male,  23.5  mm.,  female,  35  mm.;  antennae,  male, 
female,  10.5  mm.;  tegmina, male, 0  mm., female,  11.5  mm. ;  hind  femora, 
male,  13.5  mm.,  female,  17.5  mm. 

One  male,  1  female.    Lerdo,  Durango,  Mexico,  November  (L.  Bruner). 

This  species,  though  closely  allied  to  the  preceding,  is  distinguish 
able  from  it  not  only  by  its  colors,  but  by  the  greater  stoutness  of  the 
hind  femora,  more  easily  recognized  than  described.

The  type  is  H.  festivus  Scudder,  a  species  mistaken  for  //.  viridin 
Thomas  at  the  time  the  genus  was  described. 

This  genus  is  closely  related  to  Hifpnchlora  and  (Unnpylncaniha^  but 
is  separated  from  them  by  the  basal  ami)liation  of  the  margins  of  the 
subgenital  i)late  of  the  male.  One  of  the  species  indeed  (the  most 
aberrant  one)  was  originally  placed  by  Brunner  in  Hi/poelilora.  The 
genus  is  still  more  closely  allied  to  Aeoloplusj  from  which  it  is  separable 
by  the  form  of  the  pronotum  and  the  slenderness  of  the  body. 

It  is  found  across  the  United  States,  but  only  a  single  species  is 
known  east  of  the  Great  Plains,  and  that  one  has  only  been  found  on 
or  near  the  Atlantic  border.     It  is  generally  characteristic  of  the  West. 

Many  of  the  species  are  very  closely  allied  and  have  hitherto  been 
confounded  by  all  observers.  A  large  amount  of  material  now  enables 
nje  to  distinguish  them  and  to  find  characters  which  will  rarely  fail  of 
tolerably  certain  separation.

The  species  was  originally  described  from  Colorado,  Wyoming,  and 
Kansas,  and  has  since  been  reported  from  [New  Jersey]  (Chler),  [Min- 
nesota] and  Iowa  (Bruner),  Nebraska  (Thomas,  Bruner),  Kansas  and 
Colorado  (Bruner),  Beaver  Brook  and  the  (Irand  Canyon  of  the  Arkan- 
sas (Uhler);  Texas  [and  Mexico]  (Uhler);  [Ttah]  (Bruner),  and  San 
Joaquin  Valley,  California  (Coipiillet).  Localities  which  are  in  doubt 
or  in  error  are  placed  in  brackets. 

This  species  closely  resembles  H.  festivus^  but  while  generally  of  a 
little  larger  size  is  distinguished  from  it  by  the  black-marked  sulci  of 
the  pronotum,  the  generally  but  not  invariably  greater  irregularity  of 
the  markings  of  the  lateral  lobes  of  the  pronotum,  the  red  annulation 
of  the  hind  femora  (though  this  will  probably  be  found  in  some  individ 
uals  of  H.  festirus)  and  the  ground  color  of  the  head  and  pronotum,  as 
well  as  in  slight  diti'erences  in  the  abdominal  appendages  of  the  male. 
The  eyes  are  slightly  more  elongate  iu  H.  festivus  than  in  the  present 
species,  at  least  in  the  female. 

It  is  wholly  uncertain  to  what  species  belongs  the  reference  by 
Thomas'  to  an  insect  with  tegmina  only  one-third  the  length  of  the 
abdomen,  taken  in  northern  New  3Iexico  or  Colorado.  I  have  placed 
it  here  with  a  query.

This  species  differs  but  little  from  //.  /estirus,  but  has  even  more 
strikinjfly  contrasted  colors,  the  ^rcen  of  whi<'h  is  deeper  and  of  a 
bhicr  tint  and  the  femora  are  stouter.  The  face  is  yellow  with  a  slight 
l^iTeenish  tint,  coarsely  and  distinctly  punctate  with  blackish  l)rown; 
the  intercostal  interspace  below  the  antennae  is  heavily  infuscated 
and  the  usual  short  bar  below  the  eyes  is  present;  vertex  yellow,  the 
fasti;iiuni  heavily  infuscated  and  behind  it  a  wideninj*'  blackish  stripe, 
posteriorly  inclosing  a  median  yellow  thread;  antennae  fuscous,  the 
joints  feebly  and  narrowly  annulate  with  pale  ferruginous.  Pronotuuj 
yellow,  more  or  less  olivaceous,  and  on  the  metazona  often  heavily  suf- 
fused with  bright  ferruginous,  all  the  transverse  sulci  ami  i>articularly 
that  close  to  the  front  margin  heavily  marked  in  black,  which  cuts  the 
heavy  black-bordered  mediodorsal  yeHow  stripe;  upper  portion  of  the 
lateral  lobes  more  or  less  heavily  marked  with  black  on  the  prozona; 
pleural  sutures  heavily  marked  in  black.  Tegmina of  about  the  length 
of  the  abdomen,  bluish  green,  the  discoidal  and  posterior  ulnar  veins 
with  a  narrow  pallid  yellow  stripe.  Fore  and  middle  femora  duU  ferru-

broad,  dull  coral  red,  pregenicular  annulation;  hind  tibiae  greenish 
blue, the  spines  white  with  black  tips,  the  tarsi  more  or  less  testaceous. 
Sui)raaual  plate  of  male  much  as  in  //.  festivKs,  the  furcula  consisting 
of  a  pair  of  minute  but  boldly  projecting  rounded  lobes,  separated  by 
twice  their  own  width;  cerci  slightly  compressed,  subconical,  tapering 
much  more  rapidly  in  the  proximal  than  in  the  distal  half,  the  latter 
being  nearly  equal,  the  tip  rounded  but  slightly  produced  and  gently 
incurved,  the  whole  scarcely  so  long  as  the  supraanal  plate;  infracercal 
plates  incons])icuous,  apically  tapering,  almost  as  long  as  the  sui>raanal 
plate.

Of  the  long-winged  forms,  this  species  most  resembles  II.  /est ir us, 
but  is  easily  distinguished  from  it,  apart  from  the  great  difference  in

Georgia,  Morrison. 

This  species  has  been  previously  recorded  only  from  New  Jersey 
(Thomas,  Thler),  where  Uhler  says  it  is  "not  uncommon  in  the  cran- 
berry fields  of  Atlantic  County;"'  and  from  Wellesley,  Massachusetts, 
by  Morse,  who  tells  me  that  his  specimens  were  taken  in  a  very 
restricted  locality,  "a  steep  gravelly  hillside,  formiiig  the  terminal  por- 
tion of  a  part  (^f  the  gravel-plain  formation  of  Wellesley."  where  they 
were  captiu  'by  sweeping  vigorously  the  short-tufted  growth  of 
bunch  grass,  ^±uaropo(jo}i  ncoparius,  which  with  other  wild  grasses  and 
running  blackberry  vines  sparsely  clothed  the  gravelly  soil."  All  his 
specimens  were  taken  between  mid  July  and  mid  August.  Since  writ 
ing  me  this,  3Ir.  31orse  has  found  another  locality  near  the  previous, 
whereon  July  10  he  tork  both  sexes  mature  and  nymphs;  the  surround- 
ings were  similar. 

This  species  is  very  closely  allied  to  //.  pratensis,  but  differs  from  it 
in  its  shorter  tegmina  and  wings,  the  more  regularly  conical  cerci  of 
the  male,  the  slightly  different  form  of  the  supraanal  plate  and  the 
markings;  it  is  also  of  a  smaller  size.

Dr.  J.  A.  Allen  found  the  insect  in  Iowa  only  in  dry  prairies  on  tin- 
grass,  ex('ei)ting  that  the  least-marked  specimens  occurred  in  groves, 
and  there  only. 

Occasionally  a  specimen,  and  esi)ecially  a  female,  is  found  in  which 
there  is  no  trace  of  ferruginous  on  the  tegmina,  which  are  then  green 
with  a  pallid  stripe  along  the  dividing  line  between  the  discoidul  and 
anal  areas,  reminding  one  of  //.  ri  rid  is  or  H./vstinis. 

The  specimen   above  referred  to   from   Orizaba,   a    female,   differs 
slightly  in  its  somewhat  abbreviated  tegmina,  and  the  mottled  mark 
ings  of  pallid  yellow  and  green  upon  the  lateral  lobes  of  the  i)rono 
tum;  it  possibly  indicates  another  s})ecies.

IJody  relatively  short  and  stout,  considerably  enlarged  at  the  meta 
thorax,  even  in  the  male.  Head  normal,  the  eyes  moderately  distant, 
not  very  prominent  except  sometimes  in  the  male,  the  summit  well 
arched,  the  fastigium  slightly  sulcate  between  the  eyes,  the  frontal 
costa  moderately  broad,  subequal,  plane  or  nearly  plane;  antennae 
moderately  stout,  cylindrical,  equal,  slightly  longer  (male)  or  slightly 
shorter  (female)  than  the  head  and  pronotum  together.  Pronotum 
stout,  regularly  increasing  in  size  from  in  front  backward,  the  disk 
gently  convex  transversely,  the  ])rozona  slightly  and  independently 
tumid,  with  no  or  an  exceedingly  feeble  median  carina,  distinguishing 
it  from  the  Hat  carinulate  metazona ;  posterior  margin  of  pronotum 
very  obtusely  angulate,  the  angle  more  or  less  rounded;  prozona  about 
half  as  long  again  as  the  metazona,  generally  slightly  broader  than 
long  or  quadrate.  l*rosternal  spine  conical,  erect;  interval  between 
mesosternal  lobes  of  male  about  twice  as  long  as  broad,  often  clepsydral

ing from  the  same  to  (juadrate,  the  njetasternal  lobes  attingent  or  sub 
attingent  in  the  male,  a  little  distant  in  the  female.  Fore  and  middle 
femora  considerably  tumid  in  the  male,  the  hind  femora  relatively 
short  and  stout,  occasionally  furnished  interiorly  iu  the  male  with  a 
basal  tooth  protecting  the  calcaria  when  the  tibiae  are  closed  upon  the 
femora.  Tegmina  generally  completely  developed,  but  often  somewhat 
abbreviate,  rarely  lobate.  Subgenital  plate  of  male  with  the  lateral 
margins  very  strongly  ampliate  and  arched  at  the  base,  and  furnished 
with  a  distinct  but  not  very  prominent  subapical  tubercle,  the  apical 
margin  of  the  plate  forming  its  inner  base;  furcula  scarcely  or  not 
apparent;  cerci  tapering,  apically  very  slender,  simple;  terminal  seg-

The  species  was  originally  reported  from  ''between  Red  Buttes  and 
IndcixMideiice  Kock,  Wyoming,"  but  it  has  since  been  recorded  by 
Bruner  (doubtless  in  some  cases  by  mistake  for  some  of  the  allied  spe 
cies  here  tirst  separated)  from  (iarden  City,  Finney  County,  Kansas, 
western  Nebraska,  Arizona,  New  Mexico,  Montana  and  the  Pacitic 
Coast. 

According  to  T»runer,  this  species  in  the  Y^ellowstone  region  "only 
feeds  upon  two  species  of  ])lants,  as  nearly  as  I  could  ascertain  by 
observation,  viz.,  the  •i)igweed'  and  a  small  greenish  white  plant  of  a 
similar  nature.  Those  found  on  the  pigweed  are  somewhat  glaucous 
yellow,  while  those  feeding  on  the  other  plant  are  more  of  a  whitish 
color,  mingled  with  greenish  blue  instead  of  greenish  yellow,"'  the  color 
of  tiie  insects  resembling  to  a  considerable  degree  that  of  the  plants 
on  which  they  feed.

I  have  seen  no  other  males  of  this  species  since  its  tirst  descrii>tion, 
but  I  have  before  me  three  new  females,  which  from  the  greater  brevity 
of  their  tegmina  I  am  inclined  to  place  here  rather  than  in  Ae.  inrnhuU'd 
(from  which  the  females  at  least  ar'^  with  difticulty  separated),  and 
which  come  from  Colorado  (Canon  City,  Fremont  County,  .Morrison  and

obtained  on  the  plains  at  an  elevation  of  5,000  feet,  and  is  almost  wholly 
grass-green  with  the  lighter  parts  yellowish  green. 

8.  AEOLOPLUS  UNIFORMIS,  new  species. 
(Plate  VI,  Fig.  2.) 

The  color  of  the  only  specimens  seen  are  probably  changed  somewhat 
from  their  having  been  killed  in  spirits  and  are  now  of  a  light  dead  leaf 
color;  probably  in  life  they  were  uniformly  testaceous,  with  perhaps 
a  greenish  tinge.  The  pronotum  shows,  at  least  on  the  prozona,  signs 
of  a  l)road,  paler,  mediodorsal  band,  and  a  similar  band  on  the  middle 
of  the  lateral  lobes;  the  (mter  face  of  vhe  hind  femora  shows  indications 
ot  a  pair  of  dusky  transverse  bands,  mesial  and  extramesial,  and  the 
apical  half  or  more  of  the  hind  tibial  sp'ues  are  black.  The  fastigium  of 
tlie  vertex  is  scarcely  in  the  least  imi)ressed,  exce})ting  at  'ts  very  base 
between  the  eyes;  the  frontal  eosta  has  a  row  of  puncta  on  either  side,

only  of  a  rather  distinct  but  obtuse  angle  on  either  side  of  a  re»*tangu-

femora  stout  and  heavy,  hardly  if  at  all  more  than  half  as  lon^;  ajj^ain 
as  head  and  ])ronotuin  combined,  the  hind  tibiae  stout.  Abdomen 
stout,  taperin;;  and  then  apically  enlarjjed  and  considerably  upturned 
in  the  male;  sujtraanal  plate  of  male  trian^fular,  shorter  than  its  basal 
breadth,  with  a  pair  of  broad,  j;ently  tunud  ridj^es,  which  unite  into  a 
single  median  rid<4:e,  leaving  between  them  in  the  basal  half  a  shallow

plate  much  shorter  than  the  supraanal,  scarcely  perceptible. 

Body  biownish  fuscous  above  much  marked  withclay  yellow,  beneath 
almost  wholly  clay  yellow,  more  or  less  infuscated  in  the  fenmle.  The 
head  is  more  or  less  obscure  yellow,  the  vertex  at  summit  brownish  fus- 
cous, limited  at  most  to  a  narrow  median  and  two  eijually  narrow  sub 
median  streaks,  the  latter  continued  along  the  marginal  ridges  of  the 
fastigium  down  the  sides  of  the  frontal  costa,  but  at  the  aj>ical  third  of 
the  fastigium  more  or  less  interrupted  by  or  sutt'used  with  dull  red;  the 
anteniuie  are  yellow  at  base,  gradually  passing  into  fuscous.  On  the 
dorsum  of  the  thorax  and  the  *'"ont  at  least  of  the  abdomen,  the  fuscous 
is  more  or  less  obscurely  punctate  or  flecked  with  yellowisli,  and  along 
the  median  line  of  the  abdomen  there  is  a  distinct.yellowish  stripe  begin 
ning  oil  the  meso-  and  metanota  as  a  mere  thread;  the  prevailing  tint 
of  the  lateral  lobes  of  the  pronotum  is  yellowish  but  there  is  a  more  or 
less  distinct  blackish  fuscous  oblique  bar  on  the  prozona  Just  above  tlie 
middle,  merging  posteriorly  in  the  general  obscurity  of  the  metazona; 
there  is  a  distinct  broad  blackish  fuscous  oblicjue  baiul  crossing  the 
meso-  and  metapleura,  and  the  middle  of  the  sides  of  the  basal  abdoini- 
iial  segments  are  piceoas.  The  fore  and  micUUe  legs  are  fusco-luteous; 
the  hind  femora  yellowish,  more  or  less  obscured  with  fuscous  and 
spotted  with  fuscous  on  the  inner  upper  face  and  the  outer  face,  which 
is  generally  almost  black  along  its  upper  half;  hmd  tibiae  and  tarsi

Since  describing  li.  opimus^  I  have  been  able  to  jompare  it  with  the 
tyi)es  of  Thomas's  Pezotettix  obesus  and  tind  they  are  not  distinct.  The 
species  is  very  close  to  B,.  pinf/uis,  but  differs  from  it  in  its  markings, 
particularly  in  its  darker  antennae,  its  much  less  developed  median 
abdominal  stripe  and  its  dift'erently  colored  hind  tibiae,  and  also  in  the 
more  continuous  and  more  developed  median  carina  on  pronotum  and 
abdomen,  and  the  slightly  dift'ering  abdominal  appendages  of  the  male. 
It  is  evidently  the  commonest  and  most  widely  spread  of  the  species  of 
Bradynotes.  _  ,^        ,

Body  stout,  compact,  transversely  sub(piadiate,  thinly  jiilose.  Head 
large,  broad,  a  little  prominent,  with  the  eyes  fully  as  wide,  at  least  in 
the  male,  as  the  length  of  the  lateral  <arinae  of  the  metazona,  the  sum- 
mit well  arched,  raised  a  little  above  the  level  of  the  luonotum,  the 
fastigium  rapidly  descending  and  forming  an  obtuse  angle  with  the  very 
straight  and  slightly  receding  face;  eyes  rather  small  but  very  promi- 
nent in  both  sexes,  nearly  as  broad  as  long  and  no  longer  (female)  or 
scarcely  longer  (male)  than  the  anterior  intraocular  portion  of  the

nearly  as  broad  as  the  upper  asi)ect  of  the  eyes;  fastigium  feebly  con- 
vex as  far  as  the  front  margin  of  the  eyes,  in  front  of  which  it  is 
depressed;  frontal  costa  only  moderately  broad,  much  narrower  than 
tlie  interspace  between  the  eyes,  obsolescent  below  the  ocellus,  owing 
to  the  breadth  of  the  face,  the  lateral  carinae  are  more  than  usually 
divergent;  antennae  slender,  long,  about  half  as  long  as  the  botly,  even

1  have  retained  the  name  qucrcus  rather  than  louf/ipennis  for  this 
species  for  several  reasons:  It  was  first  called  by  this  name  both  by 
lliley  aud  Bruner;  it  was  first  described  in  its  earlier  stages  under  this 
name  by  Packard  (coi)ying  Bruner's  description,  which  was  unaccom- 
panied by  a  name);  and  the  name  is  a  far  more  fitting  one  than  longi- 
tHtniis,  considering  that  the  insect  appears  both  in  brachypterous  and 
inacropterous  forms,  and  that  it  is  normally  brachypterous,  as  the  basal 
divergence  of  the  tegmina  shows.  It  may  also  be  called  a  mistake  (in 
wliich  entomologists  generally  have  erred,  myself  among  them)  to  give 
any  species  of  Orthoptera  a  name  derived  from  the  length  or  brevity  of 
tiic  tegmina.  On  the  other  hand,  indubitably  the  species  was  first  fully 
described  from  mature  examples  under  the  name  longipennifi,  a  name 
given  by  Kiley  on  the  assumption  that  it  was  distinct  from  his  earlier 
iiaiu'd  miercus.  As  both  names  were  given  by  the  same  naturalist,  no 
IHTsonal  question  enters,  and  I  trust  that  in  this  settlement  of  the  ques- 
tion at  its  first  raising  all  will  agree.

Oiii-  knowledj^e  of  the  naturcil  history  of  this  8peci«*8  dei)eml8  almost 
entirely  upon  what  Uruner  wrote  in  his  lirst  aecount  of  it  in  1S,S7, 
before  it  was  named.  He  found  it  in  destruetive  numbers  in  Wasliinj;- 
ton  County,  Texas,  feedinj;  upon  the  post  oak  aiul  "completely  defoli 
atinjjf  the  trees  of  the  forest  even  to  the  very  topmost  twigs."  He  gives 
the  following  account  of  its  history  and  habits: 

The  ej;>;  pods  are  depositiMl  in  the  <;i°oiin(l  about  the  bases  of  trees  or  iiulilVrrentl.x 
scalttTi'd  about  the  siirfatM'  aiii<»ii«;  the  decaying  heaves,  etc.,  like  those  of  all  otiiiT 
groiind-hiying  species.  The  young  «'onunenfe  hatching  about  the  middle  of  March, 
and  continue  to  appear  until  into  Apiil.  After  molting  tlic  lirst  time  and  becoming 
a  little  hardened  they  immediately  climb  up  the  trunks  of  the  trees  and  bushes  of 
all  kin<l8  and  connnenee  leeding  upon  the  new  an<l  tentler  Ibliage.  They  molt  at 
least  five  or  six  times,  if  we  may  take  the  variation  in  size  and  ditVerence  in  the 
development  of  the  rudiments  of  wings  as  a  criterion.  The  imago  or  mature  stage 
is  reached  by  the  last  of  May  <tr  during  the  lirst  part  of  June. 

The  s]»ecies  is  very  active  and  shy  in  all  its  8t;i<;es  of  gn>wth  after  leaving  the  egg. 
The  larva  and  i)Upa  run  up  the  trunks  and  along  the  Iiml>sof  trees  with  considerable 
sfieed,  and  in  this  res]»ect  differ  consi<lerably  from  all  other  species  of  locusts  with 
which  I  am  actjUtaiuted.  I  am  informed  that  the  mature  insects  are  also  et|ually 
wild  and  fly  like  binls.  They  feed  both  by  day  and  night;  and  I  ant  told  by  those 
who  have  jtassed  through  the  woods  after  night,  when  all  else  was  <juiet,  that  the 
noise  ]»roduccd  by  the  grinding  of  their  Jaws  was  not  unlike  the  greedy  feeding  of 
Kwine. 

The  colors  of  the  insect  in  life  during  the  early  stages  are  given  in 
the  same  i)lace  by  Bruner  and  copied  by  l*ackard. 
liiley  had  previously  reared  the  si)ecies  iu  Missouri  on  oaks.

most  reaching  the  middle  of  the  hind  femora,  ami  nsnally  snbacnminate. 
Hind  femora  moderately  long  and  slender,  the  inferior  genicnlar  lobe 
iis  in  Melanoplns  and  the  spines  of  the  hind  tibiae  generally  lather  fewer 
ihan  in  that  genns,  nine  to  eleven,  by  exception  eight  or  twelve,  in 
number  in  the  onter  series.  Abdomen  more  or  less  compressed,  the 
•  sides  of  the  tirst  segment  with  ov  (in  some  apterons  Old  World  forms) 
without  a  distinct  tympanum,  the  extremity  in  the  nude  more  or  less 
clavate  and  recurved;  subgenital  plate  of  very  variable  form,  often 
piolonged  to  a  distinct  apical  conical  tubercle  involving  the  ai)ical 
margin,  the  lateral  margins  basally  anipliate;  cerci  very  variable,  but 
to  a  less  degree  than  in  Melano})lus,  not  infre<piently  styliform,  of  vari- 
iil>le  length;  furcula  usually  developed,  but  only  at  most  to  a  small 
(h'gree;  ovipositor  of  female  variable,  typically  exserted,  but  sometimes 
exceptionally  extended  and  at  others  i)artially  withdrawn  in  the  then 
obtusely  terminating  abdomen. 

The  limits  between  this  genus  and  Melanoplus  are  diflticult  to  formu- 
late; while  there  is  no  ditliculty  in  sei)arating  the  bulk  of  the  species 
ill  either  group,  there  are  a  number  which  tind  their  place  almost 
e(iually  well  in  either.  I  have  here  attemi)ted  to  state  anew  the  char- 
acters tirst  expressed  by  Stiil,  though  with  such  necessary  moditica- 
tions  and  expansions  as  a  far  larger  series  of  forms  entails.  I  can 
bardly  hope  that  the  conclusions  1  have  reached  will  be  sustained  at 
every  point,  but  I  am  confident  that  they  must  hold  in  the  main.  In 
doubtful  cases  I  have  endeavored  to  determine  the  atlinities  from  the 
Concurrent  study  of  both  sexes  and  not  from  either  alone,  which  would 
have  brought  about  other  and  sometimes  discordant  results;  and  I 
have  assigned  the  greatest  weight  to  the  intervals  between  the  sternal 
lohes. 

As  I  have  here  employed  a  ditferent  generic  term  from  that  in  cur- 
rent use  in  literature,  I  submit  the  following  cogent  reasons  for  the 
necessity  of  the  change: 

The  generic  name  Fodisma  was  proposed  in  a  Gallic  form  {Podisme) 


A  sin^]e  exception  is  known  to  me  in  the  subapterous  Japanese  Pndisma  dairisama.

^'IVxlisma  i.atreille  ex  i>arte/'  In  ilurmeister's  view  tln^  otiier  portion 
of  Latreille's  {^cuus  included  such  species  as  Stenohothnm  parallel  us 
and  Cliri/xoclnaon  (liHpar.^  But  these  latter  species  are  ex(dude<l  by 
Latreille's  d«^linition,and  in  his  writings  1  can  not  lind  that  he  has  ever 
mentioiH'd  any  other  species  as  appertaining  to  the  genus  than  the  two 
first  nuMitioned  above. 

The  only  other  authors  who  had  at  this  time  employed  the  term  were 
r.rulh''  in  1.s;5l*,  wIio  (as  <|Uoted  by  Fischer)  referred  to  it  only  species 
of  Stethophynni  and  StenohothrnH;  Ileyer,"  who  in  l.S.'i.'i  ( ?)  emjdoyed  it 
for  Clirj/stpchraon  tlispar ;  Stephens,''  who  in  1S3.">  had  referred  pcdcstriH' 
only  to  it;  and  Costa,'"  who  in  18.56  had  referred  to  it  four  supposed 
new  species — appulum,  contpanum,  calahrumy  an<l  conintKuis,  the  first 
two  ol'whicii  are  now  regarded  as  synonyms  of  .Icr/f/Z/^w  aeiiiiptium  L.^ 
the  third  as  probably  a  rami)hagus,  and  the  last  as  ffiornac.  Jn  view 
of  the  limitation  of  the  genus  by  Serville  (if  Latreille  ever  intended 
its  greater  extension),  this  action  of  Brulle  and  of  Costa  has  no  force, 
and  hence,  if  the  name  rczoleitlx  can  be  retained  at  all,  it  must  be  by 
regarding  one  of  the  two  original  species  as  the  type  of  Pezotettid',  the 
other  of  lUxlhma. 

As  far  as  I  can  discover,  the  first  author  to  refer  the  two  species  to 
distinct  genera  was  Fiebei,"  who  in  June,  18.13  referred  (liornac  to  his 
new  genus  Pelecyrhis^  and  pedcstris  to  PoHismn.  Also  in  18")3,  but 
later,  his  introduction  being  dated  November,  II.  Fischer '- referred  the 
former  species  to  his  new  genus  Plat}fplu/ma  and  the  latter  to  Pezotettlr. 
Fischer  has  been  generally  followed,  but  it  is  plain  that  PhitypJn/mn 
must  give  way  to  I'dcct/eliis,  which  in  its  turn  must  yield  prec«*dence  to 
Pezofettix,  of  which  (fiornae  becomes  the  type,  while  pcdestria  becomes 
the  type  of  Podisnia.

refers  to  it  pedvxtris  and  f'riffithi;  and  finally  11.  Fischer  himself  first 
used  it  in  1849'  tor /r  iff  id  a.  His  reasons  later '  for  snpplanting  Podinma 
l»y  Pezotcttix  can  not  be  defended. 

The  type  of  Vodinimi  is  therefore  OryUuK  pfdvRtrh  Tiinnaeus. 

This  ij^enus  is  more  widely  extended  than  any  (Kherof  the  Melano]>li, 
hcin;;  the  only  one  not  confined  to  America.  It  is  a  <listinctly  boreal 
t>  i>e  and  encin'les  the  jiiobe.  The  species  are  lar;;ely  confined  to  high 
altitudes  as  well  as  hi«^h  latitudes,  a  number  beinj;-  ali)ine  or  subalpine  in 
tiieir  respective  localities.  In  this  country  tlie  specii's  are  known  from 
two  widely  separated  re<;ions;  In  the  west,  the  Rocky  Mountain  region 
from  Alberta  to  northern  New  Mexico;  and  in  the  east  from  western 
Ontario  and  New  York  to  Maine.  In  Europe  they  are  largely  confined 
to  the  mountains  of  southern  ICurope  from  the  Pyrenees  to  Mount  Par- 
nassus or  to  Scandinavia:  in  Asia  their  distribution  is  less  known, 
luit  species  occur  in  eastern  Siberia  and  in  .lajian. 

In  the  following  pages  I  have  fully  described  only  the  American 
species,  w^hich  are  first  treated  se|»arately;  but  I  have  thought  well  to 
(•oini>lete  the  account  of  the  Melano[)U  by  imduding  the  Old  World 
species  as  far  as  possible,  figuring  their  abdominal  appeiulages,  giving 
a  separate  table  for  their  determination,  and  adding  brief  diagnoses  of 
two  species  which  are  unpublished.  Their  synonomy  and  distribution 
are  mostly  compiled  from  Bruimers  Prodronius  Eur.  Orthopteren.

The  colons  of  the  above  description.  Avhich  are  taken  ironi  life,  are, 
unless  otherwise  specified,  drawn  entirely  from  the  female,  as  the  sexes 
differ  considerably.  The  male  differs  in  the  following  particulars:  The 
front  of  the  head  and  thcpronotum  arc  more  yellowish,  the  prosternnm 
black,  the  spine  uniform  i)alc  green,  the  meso  and  mctasterna  bright 
green,  the  sternum  of  the  abdomen  yellowish-green,  slightly  i>aler  than 
the  thorax,  with  the  basal  border  of  the  segments  broadly  bordered 
with  black  and  the  apical  narrowly  with  fuscous;  the  whole  dorsal 
surface  of  the  abdomen  is  black  with  a  mediodorsal  series  of  yellowish- 
green  spots  and  a  triangular  spot  of  the  same  between  the  middle  and 
hind  coxae;  a  lateral  row  of  greenish-yellow  spots  on  the  tirst  eight

Excepting  Jackman,  Maine  (Harvey),  the  only  other  place  from  which 
it  has  been  reported  is  '*  British  America"  (Bruner),  but  without  further 
specification  Professor  Bruner  now  thinks  this  was  a  mistake.  Mr. 
Morse  tells  me  that  he  has  specimens  taken  on  Kataadn,  Maine,  5,200 
feet. 

In  the  White  Mountains  1  have  found  this  grasshopper  from  the 
neighborhood  of  the  snow  arch  in  Tuckermans  Ravine  (about  4,000 
feet)  to  the  base  of  the  rocky  slopes  on  the  side  of  Mount  Washington 
above  the  Alpine  Garden,  and  at  the  summit  of  Mount  Madison  (5,380 
feet)  at  about  the  same  elevation.  1  have  also  taken  it  at  the  upper 
limits  of  Huntingtons  Ravine  and  about  the  ledge  on  the  carriage  road. 
It  freiiuents  the  close  branches  of  the  dwarf  birch,  Beiula  nana,  and  is 
rarely  or  never  seen  on  the  ground.  c > 

Of  the  European  insects,  it  is  most  nearly  allied  to  Pod.  baldensis,  but 
is  a  CO  isiderably  larger  insect,  with  heavier  and  stouter  cerci  and  slen- 
derer and  longer  furcula.

Length  of  body,  male,  1(1.5  mm.,  female,  23.5  mm.;  antennae,  male, 
10.5  mm.,  female,  8.5-|-  mm.;  hind  femora,  male,  9.25  mm.,  female, 
12.75  mm. 

Two  males,  1  female.  Ithaca,  Tomkins  County  New  York,  about  400 
feet,  November,  J.  H.  Comstock;  Enfield  Falls,  Tompkins  County,  New 
York,  about  450  feet  (H.  O.  Wood  worth).  The  specimens  were  taken 
in  each  case  on  the  banks  of  streams. 

Since  this  was  written,  E.  M.  Walker  has  sent  me  drawings  of  this 
species  from  specimens  taken  at  De  Grassi  Point  on  Lake  Simcoe,  about 
50  miles  north  of  Toronto,  Canada. 

.  This  species  differs  from  the  preceding  not  only  in  coloring  and  mark- 
ings, but  in  the  greater  length  of  the  antennae  and  hind  legs,  the  brevity 
of  the  furcula,  and  the  slenderness  of  the  cerci.

The  iniblication  of  Fieber's  species  dates  from  1853  (Lotos)  ami  not 
from  1854  (Synopsis),  and  antedates  bv  several  months  the  description 
of  Fischer,  whose  name  has  been  hitherto  accepted ;  for  I'iebers  si)e- 
cies  was  published  in  the  June  number  of  Lotos,  and  the  preface  to 
Fischer's  work  is  dated  November. 

This  species  occurs,  according  to  Brunuer  von  Wattenwyl,  on  hazel 
stalks  and  bramble  bushes. 

Austrian  Alps,  especially  tbe  southern  side,  from  Transylvania  west- 
ward to  southern  Tyrol  and  the  Swiss  canton  Ticino;  and  in  the  moun- 
tiiiiious  region  bordering  the  upper  extremity  of  the  Adriatic,  eastward.

As  Brunner  points  out,  this  is  not  the  Podisma  sehmidtii  of  Fieber 
( !>*>;));  but  he  nevertheless  retains  Fieber's  name  for  it,  because  it  was 
tir.st  described  by  himself  under  that  name,  under  the  supposition  that 


116  rROCEKDiyc. .S  of  the  XA  TIONA  L  MVSE  VM.  vol.  XX. 

it  was  Fiebcr's  species,  and  because  Fieber\s  schmidtii  and  Fischer's 
W('inla.v  are  the  same.  IJy  tlie  ordinary  rules  of  nomenclature,  the 
name  srhmidtiiy  liavinjj^  been  aj)i)lied  to  one  si)ecies  of  the  genns  could 
not  snb.secjuently  be  ajjplicd  to  another,  even  if  tlie  first  were  a  syno 
nym;  but  it  is  ilouldy  incorrect  here,  since  xclnnidtii  of  Fieber  has  tlie 
priority  over  mcndax  of  Fi.s(!lier.  It  is  therefore  necessary  to  ^ivc  tlic 
l)rcsent  s])ecies  a  new  name.

fastigium  more  or  less  sometimes  very  declivent,  passing  insensibly  into 
the  frontal  costa,  always  more  or  less  sulcate  or  with  elevated  lateral 
margins,  generally  more  deei)ly  sulcate  in  the  male  than  in  the  female: 
frontal  costa  moderately  prominent,  generally  sulcate  below,  usually 
more  or  less  punctate;  antennae  slender,  of  variable  length,  but  never 
very  short,  never  longer  than  the  hind  femora,  and  rarely  if  ever  more

M'ith  ample  or<»ans  of  tlij;ht  and  those  in  which  these  orjians  are  more

characteristics,  endeavoring  thus  to  bring  into  close  <'ontiguity  those 
which  ai)peare<l  to  be  most  nearly  allied.  I  was  not  a  little  surprise<l  to 
find  in  how  few  instances  it  was  ])ossible  to  combine  the  brachypterous 
and  macroi)terons  species  in  any  one  of  these  groups.  Even  in  m<)st 
of  these,  and  especially  in  the  dawsoni  series  (itself  somewhat  heter- 
ogeneous on  either  side),  the  collocation  is  rather  forced.  The  groups 
into  which  I  have  divi<led  the  macropterous  forms  are  far  more  iiat 
iiral  than  those  of  the  brachypterous  species,  and  the  portion  of  tli«'

Tiie  present  jjenns,  so  richly  endowed  with  species,  is  naturally  very 
widely  distribntetl,  though  so  far  as  known  it  is  completely  contiiied  to 
the  continent  of  Nortli  America,  an<l  even  does  not  <H'cnr,  so  far  as 
reported,'  soiitli  of  Mexico.  Within  this  rejjion  it  is  as  widespread  as 
all  the  other  jjenera  <'(Mnbined.  It  extends  from  the  arctic  circle  in 
Alaska  and  on  the  Mackenzie  itiver.  and  trom  northern  liabrudor  and 
perhaps  southern  (Ireenland  on  tlu'  nortli,  to  the  extremity  of  Floiida 
and  southern  Mexi<*o  on  the  south,  and  fiom  the  Atlantic  to  the  Pacitlc. 
It  is,  however,  far  richer  in  species  in  the  west  than  in  the  east.  Only 
seventeen  of  the  one  liun<lred  and  thirty-one  si)ecies  are  foinnl  exclusively 
east  of  the  Mississijipi  IJiver,  thonjrh  four  other  eastern  species  barely 
cross  it;  while  in  the  Hocky  ^Mountain  re«;ion  an<l  west  of  it,  and  tliere 
only,  t'orty-nine-  s])ecies  are  known,  while  thirty  two  others  are  found 
only  west  of  the  Mississii)pi  IJiver  and  seven  western  sjtecies  barely 
cross  it  to  the  east;  six  si)ecies,  as  stated  in  our  introduction,  ran<;e 
from  Atlanti(r  to  Pacitic;  one  occurs  only  north  of  our  national  bound 
aries  in  Labrador,  while  nineteen  others  inhabit  Canada:  twelve  are 
fouuil  only  in  Mexico,  with  ten  others  which  it  possesses  in  comnuui 
with  the  Knited  States. 

These  lijjures  show  the  western  preponderance  of  the  species  better 
than  any  summary  of  thetwenty-eijiht  «itoui)s  into  which  I  have  divided 
the  jjjenus,  which,  besides  beinj»  rather  uneipial  in  the  number  of  <'on- 
tained  si)ecies, often  show  an  extremely  wide  distiibuti<Mi  or  more  than 
one  center  of  distribution,  in  the  latter  case  indicating?,  ]»erhai>s,  the 
iini)erfection  of  the  ^roupin^.  Still,  leavinjjf  out  the  live  jj^roups,  each 
of  which  contains  one  or  more  transc(UJtinental  si)ecie8,  it  will  be  noted 
that  there  are  three  others  which  compass  the  (continent — the  uiaiu'us 
(five  species),  plebejus  (five  species),  and  robustus  (live  species)  series.

1.  LAKINUS  SERIES. 

Tn  this  small  jumI  coiiipjict  jj^roiip  the  prozoiui  of  the  male  is  loiifritu- 
(liiiai,  and  the  inieiapaee  between  the  incsosternal  lobes  in  tlie  same 
sex  lonj;er  than  broad,  sometimes  twiee  as  lonj:^  as  broad.  The  anten- 
nae are  rather  short.  The  te«j^miui  are  but  little  lonjjer  than  the  pio- 
iiotum,  overlapping,  and  apically  acuminate.  The  hind  tibiae  are  jjlau- 
eous  (or  ])ale  red)  with  nine  to  twelve  (normally  ten)  spines  in  the  ouier 
series. 

The  supraanal  plate  is  aubtrianuular,  with  rather  plane  surface, 
except  for  the  rather  prominent  rid«^es  borderinj^  an<l  forming-  between 
them  the  median  sulcus;  the  furcula  consists  of  a  pair  of  pointed  slen- 
der teeth  but  little  longer  than  the  last  dorsal  segment;  the  cerci  are 
very  pe<'uliar,  enlarging  and  bullate  beyond  the  base,  but  witlu angu- 
lar mjirgins,  sulcate  inferiorl}',  compressed  but  longitudinally  convex 
exteriorly,  abruptly  narrowing  beyond  the  middle  and  incurved,  ending 
ill  a  superior,  short,  tlattenetl  linger  directed  toward  the  tip  of  the 
supraanal  jilate;  the  subgenital  plate  is  very  short  and  apically  very 
liroad,  subconical,  with  a  strongly  and  abrui)tly  elevated  though 
laterally  brief  ai)ical  margin. 

The  three  species  beh)nging  here  are  rather  bulky  insects,  rather 
above  the  medium  size  for  the  genus,  and  they  range  from  southwestern 
Nebraska  and  Colorado  to  central  Mexico.

the  iironotum,  fully  twice  as  long  as  broad,  theii  inner  and  costal  mar- 
gins about  equally  convex.  Hxtreniity  of  male  abdomen  a  little  clavate, 
considerably  recurved,  bluntly  conical,  the  sui>raa!ial  phite  triangular, 
as  long  as  broad,  the  sides  nearly  straight,  the  tip  rounded;  furcula 
consisting  of  a  i)air  of  rather  distant  processes,  broad  at  base,  with  a 
slight  tai)ering  jHuntcd  projection,  the  whole  very  small;  cerci  very 
tumid,  spherico  triangnhir  at  base,  carinate  on  the  posterior  outer 
margin,  with  a  slight,  equal,  and  blunt-ti|>ped  linger,  shorter  than  the 
base,  extending  inward  and  ui)ward  from  the  basal  swelling:  subgeui- 
tal  plate  short,  considerably  broader  at  apex  than  long,  because  the 
extreme  jjosterior  maruin  is  i)roduced  to  form  a  rather  large  rounded 
elevation  nearly  as  iiigh  as  broad. 

The  general  color  is  a  b.ownish  griseous,  tinged  below  with  yellow- 
ish; the  ar.Lennae  are  dark  and  sometimes  darker  apically;  along  the 
top  of  ihe  head  and  pronotum  is  a  blackish  fuscous  rather  broad 
median  stripe^  sometimes  broadening  in  patches,  sometimes  obsolete; 
the  upper  half  of  the  lateral  lobes  of  the  i)rozona  is  marked  by  a 
broad  blackish  fuscous  belt,  which  is  often  sei)arated  from  the  front 
margin  and  the  frequent  extension  of  the  band  to  the  eyes  by  a  nar 
row  yellow  line.  The  tegmina  are  uniforndy  grise(ms,  with  a  slender 
uicilian  line  of  alternate  yellowish  and  fuscous  tiecks,  often  obsolete. 
The  hind  femora  are  lighter  or  darker  testaceous,  with  two  verj'  broad, 
oblique,  blackish  purj^'e  belts,  which  do  not  reach  the  pale  orange

It  is  also  reported  from  southwest  Nebraska  (Bruner). 

This  species  is  very  closely  allied  to  the  last,  differing  from  it  in  its 
narrower  interspace  between  the  sternal  lobes,  the  oblique  bands  on 
the  outer  face  of  the  hind  femora,  the  more  distant  forks  of  the  furcula

2.  FLABELLIFER  SERIES. 

Ill  this  series,  one  of  the  few  which  combines  macropterous  and  bra- 
chypterous  forms,  the  male  prozona  is  feebly  or  distinctly  longitudin<il, 
occasionally  (juadrate,  the  interspace  between  the  mesosternal  lobes  of 
tlij  same  sex  varying  from  quadrate  to  half  as  long  again  as  broad,  or 
somewhat  more.  The  tegmiua  are  either  fully  developed,  though  at 
most  but  slightly  surpassing  the  hind  femora,  much  and  irregularly 
maculate;  or  half  as  long  as  the  abdomen,  heavily  marked  in  the  dis- 
coidal  field  and  subacuminate;  or  shorter  than  the  pronotum  and  then 
apically  rounded.  The  length  of  the  tegmiua  in  each  species,  however, 
is  tixed.  The  hind  tibiae  are  blue,  with  nine  to  eleven  spines  in  the 
outer  series,  or,  in  some  brachypterous  forms,  red,  with  ten  to  thirteen 
spines  in  the  outer  series. 

The  supraanal  plate  is  triangular,  rather  longer  than  broad,  with  no 
or  slightly  developed  transverse  ridges.  The  furcula  is  minute  or  sul>- 
obsole  e,  exce[)t  in  a  single  instance  where  it  is  small.  The  cerci  are 
broad,  often  excessively  broad  and  tlabellate,  enlarging  from  the  base 
toward  the  middle,  at  least  in  the  macropterous  forms,  rarely  as  much 
as  twice  as  long  as  broad,  broadly  rounded  apically.  The  subgenital 
;»i{ite  is  short  and  broad,  sometimes  with  a  slight  apical  tubercle,  the 
lateral  margins  straight,  the  apical  margin  not  elevated,  or  only  in  a 
single  instance. 

M.  rUeyiunis  is  the  most  aberrant  form,  having  very  brief  tegmiua,

the  fnrcula  longer  tban  the  last  dorsal  segment,  and  the  lateral  margii*  j 
of  the  subgenital  plate  slightly  elevated  apically. 

The  species,  six  in  number,  are  evenly  divided  between  macropierons 
and  brachypterous  forms — and  this  is  the  only  homogeneous  series  of 
Melanoplus  in  which  they  are  so — of  small  or  rather  small  size,  and  are 
found  only  in  the  district  to  the  west  of  the  Mississipi)i  aiul  mainly  in 
the  Cordilleran  region.  They  have  not  been  reported  north  of  the 
United  States,  and  a  single  species  has  been  found  to  extend  souili  of 
our  boundary  in  nortiiern  Mexico;  while  another  species  is  known  only 
from  California  and  is  the  only  one  occurring  west  of  the  Sierra  Nevada, 
(the  same  species,  M.  rtleyunuaj  mentioned  above).

Ill  tliift  series  the  male  prozona  is  slifjlitly  lonj^itudiiial,  and  t\w  inter- 
space between  the  inesosternal  lobes  exceptionally  narrow,  beinj;  nunc 
than  twice,  in  the  male.several  times,  as  lon^r  as  broad,  while  the  nieta- 
sternal  lobes  are  attinjijent  over  considerable  space  in  the  male,  approxi- 
mate in  the  female.  The  tegmina,  especially  those  of  the  male,  are 
rarely,  and  then  but  little,  maculate,  always  fully  developed  and  sur- 
passing the  hind  femora;  the  hind  tibiae  are  green  or  blue,  with  nine  to 
eleven,  usually  ten,  spines  in  the  outer  series.  The  antennae  are  of  very 
unecpial  length  in  the  two  sexes. 

The  supraanal  i)late  is  more  or  less  clypeate,  the  apex  always  well 
angulate,  and  the  median  sulcus  almost  or  quite  obsolete;  the  most 
striking  feature  is  the  furcula,  which  consists  of  a  i)air  of  long,  very 
broad,  ])arallel,  depressed  idates,  reaching  about  to  the  middle  of  the 
supraanal  plate  and  at  base  largely  concealing  it,  apically  narrowed 
])artly  or  wholly  by  their  interior  rounded  emargination;  the  cerci  are 
small,  the  apical  i)ortion  subequal,  nearly  straight,  and  about  l«alf  as 
broad  as  the  base;  the  subgenital  plate  is  somewhat  narrower  than 
long,  subequal,  apically  extended  slightly  but  not  elevated,  the  lateral 
margins  straight  and  on  a  line  with  the  upper  side  of  the  last  abdomi- 
nal segments,  the  apical  margin  well  rounded  as  seen  from  above  and 
entire. 

The  sj)ecies,  six  in  number,  are  of  medium  or  rather  large  size  and 
are  found  almost  altogether  in  the  soutiiwest;  only  one  is  known  east  of 
the  Mississippi,. and  that  only  in  the  neighborhood  of  the  main  stream.

with  the  prozona equal,  the metazona e.\pan<linj'  and  i)un('tato-rugulose; 
median  carina  slight  but  distinct  on  the  metazona.  obsolete  or  subobso- 
lete  on  the  prozona;  latenil  carinae  subobsolete;  transverse  sulci  of

little  way  beyond  the  abdomen,  surjiassing  the  hind  femora.  Suinaanal 
l)late  regularly  clypeate,  about  as  bioad  as  long;  plates  of  the  funula 
shaped  much  as  in  .1/.  hoinJitchi,  but  thickened  at  the  tip,  as  long  as 
tlie  ceici  or  nearly  two-thirds  as  long  as  the  sujuaanal  idate;  the  cerci 
have  a  triangular  base  and  a  long,  straight,  slender,  bluntly  terminated, 
ecjual  finger  extending  backward  and  upward  and  incfined  inwaid, 
starting  from  the  lower  posterior  i)orti(>n  of  the  base;  it  is  as  long  as 
the  terminal  Joint  of  the  hind  tarsi;  subgenital  plate  scoop-shai)ed, 
well  rounded  as  viewed  from  above,  the  tip  scarcely  produced,  entire. 

The  general  color  is  greenish  yellow,  sometimes  a  little  infuscated 
above,  the  head  frequently  mottled  with  fuscous;  antennae  uniform 
yellowish;  the  usual  stripe  behind  the  eye  over  the  ujiper  i>ortionof  the 
iiiteial  lobes  of  the  pronotum  is  generally  reduced  to  a  very  narrow 
dusky  stripe  next  or  on  the  lateral  carinae,  diminishing  in  breadth  i)os- 
teiiorly;  or  if  it  is  broader,  it  sometimes  invades  the  disk  rather  than 
the  lateral  lobes;  the  disk  has  a  median  dusky  line  and  the  summit  of 
the  head  a  dusky  basal  triangle.  The  tegmina  i)artake  of  the  general 
lively  tone  to  a  less  extent,  and  the  paler  me<lian  stripe,  distinct  only 
at  base,  is  seldom  flecked  intermittently  with  fuscous;  hind  femora  yel- 
low, the  upper  half  of  the  outer  face  dusky,  and  two  oblique  dusky 
l»atches  often  occur  above;  hind  tibiae  glaucous,  the  spines  white  or 
glaucous,  black  tipped,  ten  to  eleven  in  number  in  the  outer  series.

This  species  differs  fron^  the  two  preceding  by  its  slender  elongate 
form,  the  simplicity  of  its  male  furcula,  and  by  its  general  markings. 

4.  GLAUCIPES  SEUIKS. 

The  two  species  placed  together  here  have  comparatively  little  in 
common  to  warrant  their  combination  as  a  series,  and  each  should 
perhaps  be  made  the  basis  of  a  distinct  series  if  other  forms  are  found 
allied  to  one  and  tho  other:  but  falling  together  by  the  characters  given 
in  our  table,  I  have  thought  it  best  for  the  present  to  connect  them. 
They  have  these  common  characteristics: 

The  mesosternum  in  front  of  the  lobes  is  plane  in  the  male.  The  more 
or  less  maculate  tegmina  extend  only  to  the  tip  of  the  hind  femora,  and 
the  hind  tibiae  have  from  ten  to  twelve  spines  in  the  outer  series.  The 
supraanal  plate  is  simple,  without  elevated  sides;  the  furcula  is  devel- 
oped as  a  pair  of  minute  triangular  denticles;  the  cerci  are  broad  and 
short,  only  abcmt  twice  as  long  as  broad,  a  little  upcurved,  and  apically 
broadly  rounded,  while  the  subgenital  plate  is  moderately  broad,  pro- 
longed, and  scarcely  elevated  apically. 

The  species  are  of  small  or  medium  size;  one  occurs  in  Texas  and 
northern  Mexico,  the  other  from  Montana  to  Alaska.

In  this  small  group  the  ])roz<)na  of  the  male  is  (pnidrate  or  subquad 
rate,  and  the  interspace  between  the  mesosternal  lobes  is  as  in  the 
spretus  series;  in  front  of  these  lobes,  also,  the  mesosternum  of  the 
male  lias  a  central  swelling  forming  a  blunt  tubercle.  The  antennae 
are  rather  short  and  ditter  but  little  in  the  two  sexes.  The  tegmina 
are  fully  developed,  but  rather  short,  surpassing  the  hind  femora  but 
little  if  at  all,  and  clear  or  feebly  maculate;  the  hind  tibiae  are  red, 
with  normally  eleven  spines  in  the  outer  series. 

The  supraanal  jdate  is  rudely  clypeate  and  longer  than  broad;  the 
furcula  well  develoi)ed,  consisting  of  tlattened,  parallel,  more  or  less 
tapering  fingers,  half  as  long  as  the  supraanal  i)late;  the  cerci  are 
laminate  and  simple,  very  broad  and  short,  subequal,  broadly  rounded 
api<'ally,  a  little  upcnrved;  the  subgenital  plate  is  peculiar,  being 
exceptionally  Icmg  and  exceptionally  broad,  exceptionally  elevated 
and  prolonged  al  apex,  the  apical  margin  strongly  rounde<l  and 
mesially  entire,  though  in  one  species  laterally  notched,  an  exceedingly 
exceptional  feature.

Mr.  Brnner,  in  an  unpublisbed  account  of  tbis  species  kindly  placed 
in  my  bands,  says  tbat  the  i)()int  in  Montana  wbere  this  species  was 
taken  is  in  the  Yellowstone  Valley  above  the  mouth  of  the  r»ig  Horn 
liiver;  and  he  gives  the  following  points  of  ditference  between  this 
species  and  M.  atlanis: 

In  iniernudins  the  entire  body  is  more  or  less  covered  vrith  rather  lonj;  fine  hairs, 
the  thorax  is  niucli  lonj^er  than  in  ntlauis — throwinjij  the  base  of  the  posterior  femora 
considi-rably  back  of  the  middh — and  in  thi.s  resj)ecL  reseinblinj;  Pezotettix  [Milano- 
phts']  n'a.shinfjtonia»ii8  Brnner.  Tlie  mah^  cerci  are  lonj^jer  and  narrower  tli;m  iu 
atlanis,  and  are  curved  nlightly  inward  and  upward  on  the  apit-al  half;  they  are  also 
shallowly  grooved  from  the  outside.  The  last  ventral  segment  [subgenital  plate]  of 
the  male  abdomen  is  a  little  shorter  than  in  that  species,  and  the  prosternal  spine  is 
also  much  longer,  stouter,  and  more  bluntly  pointed  than  there.  The  general  color- 
i/atiou  is  much  the  f<ame  as  in  atlanis  but  darker — being  dull  brown  and  gray  above 
and  «liugy  beneath ;  there  are  no  well-defined  bands  upon  the  posieri«)r  femora,  and 
the  tibiae  are  dull  glaucous,  more  or  less  tinged  with  brown,  especially  on  the  basal 
third  and  near  the  apex. 

It  ditfers  from  3/.  atlanis,  to  whicb  it  is  most  nearly  allied,  in  the 
longer  male  antennae,  the  weaker  median  carina  of  the  pronotum,  the 
more  heavily  marked  bind  femora,  and  its  smaller  and  slenderer  form.

as  belonging  to  Walker's  Caloptenus  scripius,  and  is  tlieretore  prob 
ably  the  species  so  named  by  Cockerell '  as  coining"  from  ('olorado.  It 
is,  however,  not  that  si)ecies,  a  female  si)eciinen  of  the  present  species 
having  at  my  recjuest  been  compared  with  tlie  types  In*  Mr.  S.  llenshaw 
during  a  recent  visit  in  London.  As  compared  with  this,  he  finds  the 
true  svripiuH  to  be  "  much  larger,  heavier,  and  with  shorter,  heavier, 
and  more  clumsy  i)rosternal  spine;  thoracic  carinae,  especially  the 
median,  shai])er  and  more  prominent;  cui>s  of  upper  valves  ot  ovii)osit()r 
much  deeper;  lower  valves  much  heavier.*'  He  also  compared  this 
with  the  ty[)e  of  Walker's  Caloptenus  hilifuratu.s  and  found  it  the  same,

Tbe  publisbed  accounts  add  very  little  to  tbe  above  range  of  distri- 
bution, except  tbat  it  is  rejiorted  from  (^>uebec  (Provancberj,  nortbern 
Californiit  (Packard),  Nevada  (Scudder),  and  soutb  as  far  as  middle 
Florida — probably  by  error  (Packard). 

It  is  i)robable,  tberefore,  tbat  it  is  found  in  every  part  of  tbe  continu- 
ous district  of  tbe  United  States,  excepting  in  tbe  soutbernmost  Atlantic 
States  and  most  of  California,  being  tbus  limited  very  mucb  as  M.ftinin- 
ruhrnm  ;  it  extends  also  into  central  Mexico,  and  nortb  of  our  boundary 
is  fountl  from  Atlantic  to  Pacific  as  far  at  least  as  latitude  o(P  (except- 
ing Newfoundland),  and  on  tbe  Pacific  sidereacbes  nortb  to  tbe  Yukon 
River  and  probably  tbe  Lower  McKenzie. 

Next  to  .1/.  spretus  tbis  is  our  most  destructive  locust,  and  east  of 
tbe  ^lississippi  jirobably  tbe  only  one  ever  doing  mucb  damage.  Its 
injuries,  bowever,  are  not  for  a  moment  to  be  compared  witb  tliose 
inriicted  by  M.  sprettiSy  for,  tbougb  possessing  good  powers  of  tliglit 
and  on  rare  occasions  known  to  migrate  in  swarms,  its  injuries  can  only 
be  classed  as  local,  and  tbey  are  never  so  serious  as  tbose  inflicted  by 
M.  S2)yettis :  nevertbeless  tbey  are  by  no  means  sligbt,  and  immense

or  iiiountaiiious  regrions  .  .  .;  it  seems  also  to  prefer  a  wooded  or  mixed 
country  to  the  open  juairies  or  plains." 

This  is  one  of  the  most  variable  of  the  Melanopli,  and  it  is  some- 
times ditticult  to  distinjiuish  from  its  immediate  allies.  The  abo.e 
description  is  drawn  up  primarily  from  Eastern  examples  which  came 
from  the  rejiion  from  which  the  species  was  origfinally  described. 
Specimens  from  the  dry  plains  of  the  West  (especially  noted  in  those 
from  (Jtah)are  decidedly  paler  and  more  cinereous  in  aspect  than  those 
from  relatively  fertile  country,  and  they  have  often  a  Havous  stripe 
borderiufi'  the  eye  and  continued  ahnig"  the  position  of  the  lateral 
carinae:  a  similar  but  not  so  striking;:  a  cinereous  hue  attaches  to  those 
tliat  occur  in  sandy  localities  in  the  Eastern  States,  as  along  the  sea 
margin.  The  exact  contrary  is  shown  in  Canada  just  east  of  the  Rocky 
Mountains,  where  the  s[>ecimens  are  exceedingly  dark  in  color,  almost 
blackish  fuscous,  with  heavy  fasciation  of  the  hind  femora: '  but  here 
again  a  difference  of  anotlier  sort  occurs  as  one  i^asses  eastward,  speci- 
mens from  Laggan  and  Bantf  almost  invariably  having  relatively  long 
and  slender  male  cerci,  while  at  Calgary  all  that  have  been  seen  (with 
a  very  few  from  the  former  localities)  have  male  cerci  hanrv  more 
than  half  as  long  again  as  broad.  Specimens  from  Mexico,  vever, 
agree  very  closely  with  those  from  Xew  England. 

Sjjecimens  with  green  hind  tibiae  have  been  seen  by  me  from  the 
White  Mountains,  New  Hampshire,  but  not  from  the  summits  (except 
Krarsa-rge  3,l.*51  feetj,  from  the  vicinity  of  Boston,  at  Provincetown, 
and  on  the  island  of  Nantucket,  Massachusetts,  from  Laggan,  Alberta, 
the  Yellowstone  region,  Montana,  Wyoming,  Nebraska,  Missouri,  C(»lo- 
rado,  from  the  Salt  Lake  valley  and  American  Fork  Canyon  (9,500  feet), 
Utah,  Texas,  and  Chihuahua,  Mexico.  Specimens  with  dark  blue 
hind  tibiae  have  been  seen  from  Iowa.  Colorado,  American  Fork  Canyon, 
rtah,  and  Texas.  In  nearly  or  quite  all  these  cases  specimens  with 
red  liind  tibiae  predominated  in  the  same  district. 

According  to  Rilev  the  first  mature  insects  observed  one  vear  about 
St.  Louis,  Missouri,  appeared  July  12,  and  deposited  eggs  by  July  20. 
The  eggs  had  a  ([uadrilinear  arranjiement  in  the  pod,  hatched  in  from 
three  to  four  weeks,  and  the  young  took  eighty  days  to  reach  maturity. 
He  says  he  has  proved  that  the  insect  is  there  double-brooded,  though 
I  find  no  data  published  by  him  in  support  of  the  statement,  and  the 
above  facts  drawn  from  his  writings  militate  against  it.  Bruner,  how- 
ever, agrees  with  it,  saying  that  in  the  District  of  Columbia  a  second 
brood  ai)])ears  in  the  late  autumn,  composed  of  smaller  and  darker 
individuals.     I  have  seen  nothing  of  the  kind  in  New  England. 

The  points  in  which  the  unfiedged  locusts  dift'er  from  the  same  stages 
in  M.  sprctus  and  M.  femur  ruhium  are  explained  and  figured  in  the 
tust  rei)ort  of  the  United  States  Entomological  (Joramission.  in  which 
many  other  interesting  points  regarding  this  species  will  be  found. 


Speiiniens  from  Sutlbury,  Untario,  are  siuiilarly  dark.

Twohundred  and  seventy-six  nniles,  i30females.  I  refrain  from  giving 
in  detail  the  localities  from  which  1  hav  e  seen  specimens, both  on  account 
of  their  number  .md  because,  from  the  irregular  distribution  of  the 
insect  in  different  years,  such  details  would  have  little  value  without 
dates,  which  are  not  always  accessible:  farther  on,  however,  I  give  all 
that  are  of  special  interest. 

The  name  of  this  species  is  to  be  credited  to  ^l\\  V.  W.  Thler,  who 
)>laced  it  in  his  collection  thirty  or  more  years  ago  and  communicated 
it  to  various  persons,  who  used  it.  sometimes  in  an  incorrect  form.  The 
original  siJecimens  were  received  from  Mr.  Kobert  Kennicott,  and  were 
obtained  by  him  from  a  migratory  horde  which  settled  in  the  then  Red 
INver  settlements,  now  Winnipeg  and  vicinity,  Manitoba.  On  Mr. 
rider's  generous  transfer  of  his  collection  to  me,  these  specimens,  with 
their  history,  came  into  my  possession,  and  I  now  have  them  with  his 
(•riginal  labels.     One  has  been  placed  in  the  National  Museum. 

It  was  thus  known  from  the  start  as  a  migratory  insect,  and  com- 
paring it  with  any  species  of  the  genus  one  would  at  once  be  struck 
with  the  greater  length  of  the  tegmina  and  wings.  These  were  meas- 
ured bv  liilev;  in  fortv-eight  males  the  tegmina  extended  bevond  the 
abdomen  5  to  10  mm.,  with  an  average  of  7.0  mm. :  in  ninetj'-nine  females 
they  ranged  from  •'»  to  10  mm.  beyond  the  abdomen,  the  average  (».7  mm. 

It  is  now  well  known  as  the  "Kocky  Mountain  Locust "  or  destructive 
locust  of  the  States  in  the  western  half  of  the  ^Mississippi  Valley.  It 
has  beeu  njore  written  about  than  any  other  American  Orthopteron,  and 
was  specially  discussed  by  the  Tuited  States  Entomological  Conunission, 
organized  to  devise  methods  of  checking  its  ravages  after  a  study  of  its 
natural  history.  It  forms  thp  almost  exclusive  subject  of  their  tirst 
report,  and  occupies  a  considerable  space  m  their  second.  AlthougU  a 
considerable  body  ot  the  evidence  adduced  by  them  is  contradictory 
and  in  part  of  doubtful  application  to  this  ])articular  species,  their  con- 
clnsiojiis  are  in  very  large  measure  well  founded.  As  ai)pears  from  a 
study  of  their  work  and  other  available  material,  the  following  conclu- 
sions mav  be  fairlv  drawn : 

(1)  Th(i  home  of  the  species  is  in  favorable  localities  in  the  elevated 
region  of  the  Ilocky  Mountains  or  immediately  boroering  it  from  the 


188  PEOCEEDl^GS  01    TUE  SAJWSAL  MUSEUM.  vol.xx- 


South  Saskiitcliewaii  to  AVyoiiiiiij;,  iiiclusivt*,  juid  in  tlie  Kockj'  Moun- 
tain region  projuT  in  Colonulo  and  Ttah. 

(2)  In  certain  years,  especially  in  dry  seasons,  between  mid-July  and' 
mill  September,  migratory  hordes  of  incr<'dible  ninnbers  and  of  both 
sexes  pass  from  their  natural  breedin*;  «?r(mnds  to  the  east,  southeast, 
and  south,  conveyed  by  the  winds  (toward  which  they  head)  over  a 
greater  or  less  and  sometimes  a  vast  extent  of  country  frou)  Lake  Win- 
nijieg  to  or  almost  to  the  (inlf  of  Mexico,  rarely  ]>assii<;i'  fartlier  east 
than  lon<»itu«le  U3^,  and  devastating-  the  countries  they  reach  to  an 
alarming  extent,  sometimes  in  places  abstdutely  destnninji:  all  standing 
crops  and  defoliating  fruit  trees. 

(3)  As  they  rise  for  flight  from  home  onlj'  in  dry  clear  weather  (when 
the  prevailing  winds  are  from  the  north  or  northwest),  they  do  not  seri 
ously  invade  the  regions  (mostly  infertile)  to  the  west  of  their  home. 

(4)  The  invaders  extend  or  may  extend  their  tiights  to  a  distance  oti 
at  least  500  miles  from  their  jjoint  of  origin,  but  there  is  no  <lear  evi- 
•lence  to  show  that  (as  claimed  by  the  C(unmission)  they  extend  it  to 
dcmble  that  distance. 

(.">)  They  deposit  their  eggs  throughout  the  invaded  territory,  but 
their  descendants  therein  of  the  succeeding  year  not  only  do  not  effect 
a  tithe  of  the  damage  of  the  i)receding  year  (although  on  the  ground 
earlier),  but  when  winged  move  about  in  swarms  from  place  to  idace, 
their  i)revailing  <lirection — at  least  during  the  earlier  part  of  the  sea- 
son— being  the  reverse  of  that  of  their  parents;  but  even  when  they 
alight  and  <*over  the  ground  they  are  far  less  harmful  than  were  their 
invading  i)arents. 

(())  With  few  exceptions,  movements  on  the  wing  are  with  or  nearly 
with  the  wind,  and  are  usually  made  in  clear  weather  between  9  a.  m. 
and  4  \).  m.,  but  they  are  sometimes  certainly  made  at  night. 

(7)  lielatively  sj>eaking.  exceedingly  few  of  the  returning  swarms 
ever  reach  the  true  home  of  the  species.  As  a  rule,  they  show  signs  of 
enfeeblement  and  deposit  few  eggs  in  the  invaded  region,  so  that  their 
descendants  on  tht  invaded  soil  grow  less  and  less  numerous,  and,  in 
eftect  if  not  in  fact,  die  out  in  the  course  of  a  very  few.  i)robably  at 
most  two  or  three,  years. 

I  can  add  almost  nothing  to  the  facts  given  by  the  Entomological 
Commission.  It  may  be  worth  while  to  state  that  in  1S77  I  took  or

I  have  also  seen  specimens  fiom  tiie  fcdlowing  localities,  which  have 
some  special  interest:  Fort  Hayes,  ivansas,  collected  by  J.  A.  Allen  ia 
June.  1871  (not  heretofore  reported  in  Kansas  in  this  year);  Preston, 
Texas,  Cajjtain  Pope,  ]May  1."),  1854  (uecessarily  the  i)rogf^nyof an  invad- 
ing Hight  in  a  previous  year,  and  none  are  recorded  either  in  Texas  or 
Arkansas  between  18r)0  and  isr)3,  inclusive);  Ringgold  P.arracks.  (ui 
the  Lower  Rio  Grande,  A.  Schott.  juesumably  also  in  the  s|)ring  of 
18.j4,  when  the  ^lexican  lioundary  Commission  was  at  work  there; 
Sonora,  Mexico,  A.  Schott,  and  San  Lorenzo,  Chihuahua,  Mexico,  F. 
Palmer,  showing  that  it  reaches  Mexico,  and  that  too  even  as  far  west 
as  Sonora.  I  have  also  a  single  specimen  from  California  from  Mr.  II. 
Kdwards,  but  it  may  have  been  taken  in  that  part  of  the  State  east  of 
the  Sierra  Nevada. 

A  tabular  view  of  *' locust  vears''for  the  different  States  will  be 
found  in  the  lirst  report  of  the  Commission,  page  113. 

This  insect  is  normally  single  brooded;  the  eggs  winter  and  the 
earliest  (those  in  warm  exposures)  hatch  in  Texas  from  the  middle  to 
the  last  of  March,  and  '•  continue  to  hatch  most  numerously  about  four 
(lays  later  with  each  <legree  of  latitude*  north,"  so  that  in  Montana  and 
Manitoba  it  is  from  the  middle  of  ^lay  to  the  first  of  June.  This  is  in 
the  temporary  region ;  probably  it  is  correspondingly  later  on  the  higher 
levels  of  the  permanent  breeding  grounds.  The  young  reach  maturity 
in  sixty  to  seventy-two  days,  to  judge  from  those  reared  in  confine- 
ment, and  after  a  few  days  coui»le,  the  female  beginning  to  lay  eggs  in 
about  a  fortnight  thereafter.  The  eggs  are  laid  in  almost  any  kind  of 
soil,  but  by  preference  in  bare,  sandy  places,  arid  in  their  permanent 
home  the}'  show  a  preference  for  the  shaded  base  of  shrubby  plants; 
they  are  laid  in  a  sort  of  pod,  with  a  quadrilinear  arrangement  therein. 
Several  pods  may  be  laid  by  a  single  female,  Mr.  Riley  having  on 
three  different  occasions  obtained  two  pods  from  single  females  in  coq- 
linement,  laid  at  intervals  of  eighteen,  twenty  one,  and  twenty-six  days, 
respectively. 

The  migratory  instinct  appears  to  be  strongest  within  about  three 
weeks  from  the  time  of  attaining  maturity,  or  shortly  before  and  during

7.  DEVASTATOR  SEIMES. 

This  jiroup  is  «-onjiM»sed  of  very  closely  related  spe<'ies.  often  difticult 
to  distinguish,  in  which  the  male  pn)Zona  is  quadrate  or  subt|uadrate, 
and  the  immature  markings  on  the  lateral  lol)esof  the  i)ronotum,  char- 
acteristic of  the  young  <>f  Melanoidus,  occasionally  persist  in  the  adult 
and  especially  in  the  female;  the  interspace  between  the  mesosternal 
lobes  of  the  mah*  is  always  longer  than  broad,  varying  from  a  little  mon* 
than  half  as  long  again  to  a  little  more  than  twice  as  long  as  broad. 
The  tegmina  are  always  fully  developed  and  generally  maculate;  tin* 
hind  tibiae  are  variable  in  color,  often  within  the  species,  and  hav** 
from  nine  to  thirteen  spines  in  the  outer  series. 

The  supraanal  plate  is  similar  to  that  of  the  femur-rubrum  series, 
but  less  constricted  in  the  middle  ami  shorter:  the  furcula  consists  ot 
a  ]»air  of  i>arallel  or  subparallel.  tapering,  tolerably  long,  generally 
flattened,  acuminate  lingers;  the  cerei  are  very  simple,  rather  small. 
not  reaching  the  tip  of  the  supraanal  jdate,  slender  and  subecjual. 
tapering  feebly  in  the  basal  half,  equal  beyond,  bluntly  roun<led  at  tii». 
and  a  little  incurved,  generally  slightly  sulcate  or  dimpled  apically  on 
the  outer  side;  the  subgenital  plate  is  broad,  of  subequal  breadth,  but 
slightly  broader  at  base  tlian  at  tip.  apically  elevated  and  the  ajucal 
margin  well  rounded,  thickened,  and  weakly  notched. 

The  insects  are  of  small  or  medium  size,  and  the  s[)ecies.  eight  in 
nund)er,  are  separable  with  dithculty.  They  are  contine<l  almost 
exclusively  to  California,  a  single  one  of  them  only  occurring  also  a 
little  beyond  its  boundaries  in  the  neighboring  regions.  It  is  the  char- 
acteristic groui)  of  the  Pacific  coast.

acutangulate  apex  (its  production  not  shown  in  the  figure),  a  rather 
slender,  not  very  deep,  percurrent,  median  sulcus,  with  sharp  but  not 
high  walls,  &,nd  a  pair  of  i)arallel,  slight,  short,  apical  ridges:  furcula

supraanal  plate;  infracercal  plates  rather  broad  and  sulcate,  but  con- 
cealed by  the  recumbent  cerci  except  apically,  as  they  are  a  little  larger

mm.,  female,  12  mm. 

Two  males,  3  females.  San  Francisco,  California,  October.  November 
(L.  Bruner;  S.  n.  Scudder). 

This  species  is  very  closely  related  to  the  last,  and  with  larger 
material  may  prove  to  be  the  same :  but  the  anal  cerci  are  faintly  larger 
apically  than  mesially  in  the  present  form,  while  in  M.  sierranus  they 
retain  apically  their  mesial  narrowness.

The  species  has  also  been  reported  from  various  other  counties  in 
California,  mostly  ii  the  central  jwrtions  of  the  State,  such  as  Fresno, 
Yuba,  Xapa  (Kiley),  Sutter,  San  Joaijuin  (Coquillett),  and  Lake  Talioe, 
Placer  County  (Scudder),  as  well  .is  from  districts  immediately  a<ljoin- 
iug  California,  as  the  adjacent  parts  of  Oregon  (Bruner),  IJeno,  Washoe 
County,  and  (ilen  Brook,  Douglas  County,  Nevada  (Scudder),  and  Ari- 
zona (Bruner). 

It  has  also  been  stated  to  occur  in  Colorado  (Scudder),  Kansas,  North 
Dakota,  northwest  Wyoming,  and  Montansi  (Bruner),  Idaho  (Bruner, 
Milliken),  and  in  Ctah  in  the  Salt  Lake  Valley  (Scudder)  and  Nephi, 
Juab  County  (Kiley);  but  certainly  in  some,  and  probably  in  all  the.se 
cases,  the  insect  reported  was  mistakenly  supposed  to  be  this  species. 

Coquillett  describes  a  dipterous  parasite,  ISarvophiuja  opifera.,  as  found 
in  this  species,  and  gives  in  the  Twenty-seventh  Bulletin  of  the  Ento- 
mological Bureau  at  Washington  a  full  account  of  the  ravages  of  this 
locust  in  California,  where  they  appear  to  do  most  damage  to  vineyards 
and  to  deciduous  fruit  trees,  the  latter  of  which  always  suffer  the  most 
in  the  vicinity  of  grain  fields,  upon  which  the  migrating  swarms  appear 
always  to  descend,  attracted,  perhaps,  by  their  color.  Grain,  however, 
appears  to  suffer  relatively  little  at  their  hands,  though  alfalfa  proves 
attractive. 

A  description  of  the  colors  of  the  living  young,  by  Mr.  Coquillett, 
will  be  found  in  the  report  of  the  United  States  Entomologist  for  1885, 
page  293. 

The  species  fs  an  exceedingly  variable  one,  and  with  limited  material 
it  would  be  difficult  to  believe  that  there  was  but  a  single  species,  so 
widely  different  is  the  appearance  of  the  extremes.  This,  I  suspect, 
will  prove  partly  dependent  upon  station,  though  the  different  forms 
into  which  I  would  provisionally  separate  the  species  appear  to  be 
found  indifferently  in  almost  all  parts  of  the  State,  though,  as  far  as  the 
collections  before  me  show,  all  appear  to  be  more  abundant  in  the  cen- 
tral and  northern  i)ortions. 

There  is  first  the  dark  and  rather  small  form,  which  is  prevalent 
about  San  Francisco,  and  which  may  be  called  J/,  d.  obscnrus  (Plate 
XIII,  figs.  3,  4).  It  is  also  found  in  Sierra,  Placer,  Marin,  Sacramento, 
Eldorado,  and  Alameda  counties,  as  well  as  iu  Siskiyou  County,  iu  the 


N0.1124.  REVISWy  OF  THE  MELASuPLl—SClDDER.  l!)9 


iiortl',  and  Los  Angeles  County,  in  the  south.  Tlie  tyi)ieal  forms  are 
very  dark,  having  tegmina  surpassing  but  little  the  hind  femora,  with 
meager  niaculation  of  the  diseoidal  area,  rarely  at  all  cinereous  in  the 
basal  half;  the  hind  tibiae  are  variable  in  color. 

A  second  form,  which  api)ears  to  be  the  widest  spreail,  occurring  in 
nearly  every  county  in  which  tlie  species  has  been  found,  from  Shasta 
to  San  iJiego  and  from  Marin  to  Sierra,  i.<  of  a  decidedly  cinereous 
aspect,  with  abundant  and  generally  rather  contused  maculation  in  the 
discoidai  area  of  tlie  te^'mina,  which  usually  nuich  surpass  the  hind 
femora;  the  hind  tibiae  are  variable,  but  rarely  glaucous.  This  tbrm 
best  represents  the  original  types  of  the  species  when  tirst  described, 
and  being  also  the  most  common  may  bear  the  name  ,1/.  d.  typicalis 
(Plate  XIII,  tig.  5).    It  is  of  medium  size. 

The  third  form  is  also  of  medium  size  and  is  very  closely  related  to 
the  last,  and  often  hardly  distinguishable.  It  may  be  called  M.  fl. 
atfinis^  (Plate  XIII,  tig.  0).  It  difl'ers  principally  by  its  shorter  teg- 
niina,  which  rarely  surpass  the  hind  femora,  and  which  are  very  shari)ly 
maculate,  with  welldelined  s])ots,  and  the  hind  tibiae  are  usually  glau- 
cous, occasionally  luteous.  I  have  seen  si)ecimens  from  Sierra,  Sacra- 
mento, and  Los  Angeles  counties. 

The  fourth  form  is  by  far  the  largest  and  the  most  heavily  marked  of 
all,  besides  being  of  a  rather  light  tint,  in  which  the  dark  maculations 
a])pear  with  the  greater  distinctness,  and  it  may  accordingly  be  known 
as  M.  d.  consjyicHu.s  (Plate  XIII,  fig.  7).  It  appears  much  like  an  exag- 
gerated form  of  the  last-mentioned  type,  and  has  a  more  i^rominent 
head,  much  longer  tegniina,  which  well  surpass  the  hind  femora,  and 
ample  wings,  so  that  I  suspect  the  migrating  tiights  will  be  found  to  be 
composed  mainly  or  exclusively  of  this  form ;  the  pronotum  is  unusually 
clear  of  lateral  markings,  and  the  hind  tibiae  are  pale  glaucous.  It  has 
not  been  found  south  of  the  center  of  the  State  (nor  have  any  migratory 
hordes  been  reported  there),  and  indeed  only  in  the  central  portions 
and  the  elevated  districts,  namely,  in  Sacramento,  Eldorado,  Amador, 
and  Merced  counties.

8.  IMPUDICUS  SEKIES. 

This  group  is  composed  of  a  single  species  of  medium  size,  and  is  more 
nearly  related  to  the  next  group  than  to  any  other.  The  prozona  is 
slightly  longitudinal  in  the  male.  The  interspace  between  the  meso- 
sternal lobes  in  the  same  sex  is  nearly  half  as  long  again  as  broad  and 
the  metasternal  lobes  are  only  approximate.  The  tegmina  are  fully 
developed  and  surpass  the  hind  femora.  The  hind  tibiae  are  red  and 
have  eleven  to  thirteen  spines  in  the  outer  series.

l».  ARIDUS  SERIES. 

In  this  group  the  antennae  of  the  male  are  exceptionally  long  and  the 
pro/ona  is  distinctly  longitudinal.  The  interspace  between  the  meso- 
sternal  lobes  in  the  same  sex  varies  from  subfjuadrate  to  half  as  long 
again  as  broad,  while  in  the  female  it  varies  from  distinctly  transverse 
to  much  longer  than  broad.  The  pronotum  is  posteriorly  truncate  or 
subtruncate,  usually  broadly  emarginate.  The  tegmina  are  not  only 
abbreviate  but  rarely  as  long  as  the  pronotum,  lateral  and  distant. 
The  hind  femora  are  long,  and  the  hind  tibiae  light  colored,  with  eight 
to  twelve,  generally  about  ten,  spines  in  the'outer  series. 

The  supraanal  plate  of  the  male  is  triangular  and  rather  simple;  the 
last  dorsal  segment  is  obliquely  and  deeply  sulcate  on  either  side  of  the 
base  of  the  furcula,  which  consists  of  a  pair  of  very  slender  parallel 
tiugers  or  spines  of  variable  length,  but  never  very  long;  the  cerci 
rapidly  narrow  at  the  base  to  a  long  and  exceedingly  slender  incurved 
blade,  hardly  as  long  as  the  supraanal  plate,  and  narrower  by  far  than

The  female,  collected  by  Xantus  (presumably  at  Cape  St.  Lucas),  is 
the  one  referred  to  by  me  in  my  original  description  of  M.  cridus  ;is 
belonging  to  that  species,  but  it  dift'ers  from  it  (and  agrees  with  M. 
hfonphreysii)  in  the  emarginatiou  of  the  posterior  border  of  the  ])ro- 
notuni,  and  difiers  from  both  in  the  greater  robustness  of  the  body, 
especially  in  the  metathoracic  region.  It  is  quite  possible  that  the 
male  and  female  here  brought  together  do  not  properly  belong  to  one 
species;  there  is  great  disparity  in  size  and,  as  the  description  shows, 
some  unusual  disagreements  between  sexes  of  the  same  species;  but 
they  certainly  belong  in  close  proximity,  even  if  distinct ;  if  they  should 
prove  di.stinct,  the  name  should  be  retained  for  the  male,  from  which 
the  description  (especially  in  colors)  has  principally  been  drawn.

10.  INDIGENS  SERIES. 

In  this  group,  consisting  of  only  a  single  species  of  medium  size,  the 
prozona  of  the  male  is  very  longitudinal  and  the  interspace  between 
the  mesosternal  lobes  of  the  same  sex  only  slightly  longer  than  broad. 
The  antennae  of  the  male  are  almost  as  long  as  the  hind  femora.  The 
tegmina  are  abbreviate,  about  as  long  as  the  pronotum,  subelliptical 
with  rounded  apex.  The  hind  tibiae  are  greenish  and  have  ten  to 
twelve  spines  in  the  outer  series. 

The  extremity  of  the  male  abdomen  is  hardly  clavate  and  the  supr;i 
anal  plate  triangular  with  distinct  median  sulcus  and  mesially  notched 
lateral  margins;  the  furcula  consists  of  a  small  pair  of  tapering  fingers: 
the  cerci  are  large  and  broad,  almost  equally  broad  throughout,  and 
ai)ically  rounded,  nearly  straight;  the  subgenital  i)late  is  broa^l  and 
short,  the  apical  margin  elevated  to  a  blunt  tubercle. 

The  single  species  occurs  in  Idaho.

(^)f  medium  size,  brownish  fuscous  above,  sordid  testaceous  beneath. 
Head  a  little  i)rominent,  olivaceo-testaceous  tle(;ked  with  fuscous,  above

One  inalo.     Siilmon  City,  Leiiihi  County,  Idaho.  August  (L.  IJruner). 

This  spetdes  has  a  chjse  gen«*ral  resemblance  to  Vodismn  hKirshallii 

witli  its  much  shorter  antennae  and  wide  separation  of  the  uiesosternal 

lobes. 

11.  MANCrS  SERIES. 

In  this  group,  composed  of  si)ecies  mostly  of  small  size,  the  prozona 
of  the  male  varies  from  quadrate  to  distinctly  lougitmliual,  and  the 
interspace  between  the  mesosternal  lobes  of  the  same  sex  vaiics  from  a 
little  longer  than  broad  to  more  than  twice  as  long  as  broa«l.  Tl  e 
antennae  of  the  male  are  rarely  as  long  as  the  hind  femora.  The  teg 
niina  are  always  abbreviate,  about  as  long  as  the  i)ronotuu),  usually 
rather  broad  and  either  ungulate  or  nu)re  or  less  acuminate  at  tip.  The 
liind  tibiae  are  red,  rarely  greenish,  and  have  nine  to  sixteen,  more  com 
iDonly  about  eleven,  spines  in  the  outer  series. 

The  extremity  of  the  male  abdomen  is  usually  very  feebly  <'lavatr, 
and  tiie  supraanal  plate  usually  triangular  and  rather  tlat  ex(ei»t  fortlie 
subnu'dian  ridges;  but  it  is  sometimes  long  subclypeate  with  margins 
more  or  less  raised;  the  furcula  always  consists  of  a  feeble  or  ratlu-r 
feeble  pair  of  denticulations;  the  cerci  are  generally  rather  small,  some- 
times nearly  equal,  at  others  tapering  more  or  less  in  the  basal  half, 
but  rarely  anywhere  very  slender,  generally  incurved  or  inbent,  and 
occasionally  somewhat  arcuate  as  seen  laterally,  always  well  rounded 
apically  and  geuerally  exteriorly  sulcate  on  the  apical  half;  the  sub 
genital  plate  is  broad,  generally  also  short,  subccmicalor  ^ubpyramidal, 
the  lateral  and  apical  margins  in  the  sauie  i)lane  and  entire. 

The  species  are  ti  ve  in  number  and  have  together  a  wide  range,  though 
all  but  one  are  rather  local,  so  far  as  kuown.  Tiie  one  which  is  widely 
distributed  occurs  from  ]!!febraska  and  Kansas  to  Texas  in  the  West. 
and  from  southern  New  England  and  central  New  York  to  Virginia  in 
the  East.  The  other  species  are  knowu  respectively  from  Lower  Call 
fornia,  Colorado,  Idaho,  and  northern  New  England,  but  the  last  is  also 
reported  from  Illinois. 

This  series  represents  in  brachypterous  forms  the  glaucipes  seiies  in 
macropterous,  and  in  an  ideal  arrangement  the  series  should  not  be  so 
widely  separated  as  here.

It  lias  also  been  reported  from  New  Jersey  (Smitb),  Ithaca,  New  York 
(Comstock),  Normal,  McLean  County,  Illinois  (Thomas),  various  i)Mrts 
of  Kentucky  (Garman),  Topeka,  Shawnee  County,  Kansas  (P>runer), 
and,  with  doubt,  by  Thomas  from  Colorado  "subalpine''  and  southern 
Colorado. 

The  si)ecies  varies  to  a  considerable  degree,  as  appears  in  part  from 
tlie  above  description.  Texan  specimens  have  the  te«;:mina  uniformly 
less  acuminate  apically  and  a  longer  furcula.  Occasionally  the  tegmnia 
are  considerably  longer  than  the  i)ronotum,  as  appears  especially  in  a 
pair  sent  me  by  Professor  11.  Garman  from  Kentucky.  Specimens 
from  southern  New  England  appear  uni/orraly  somewhat  smaller  tlian 
others,  while  there  is  no  difference  in  size  between  specimens  from 
Maryland  and  Texas. 

Walsh,  supposing  the  species  here  described  as  M.  irtfhhii  to  be  the 
true  ^f.  sciidderi,  immed  the  present  species  in  his  letters  rtzotittir 
nibricrus,  and  I  still  ])ossess  several  specimens  sent  me  by  him  in  18(>.j 
under  that  name.  Examination  of  the  types  of  Tliler  and  Thonuis 
show  that  sciulderi  and  unicohr  are  identical,  as  McNeill  thought. 

Kiiey  states  that  this  species  attains  nmturityin  the  vicinity  of  Saint 
1  ouis,  Missouri,  about  September  1,  and  begins  to  oviposit  on  Septcm 
bev  24.  The  eggs  have  a  quadrilinear  arrangement  in  the  pod.  Uliler 
found  it  abundant  near  Baltimore,  Maryland,  on  *'the  sides  of  higli 
hills,"  Beutenmiiller  about  New  York  City  in  "dry  places,"  and  Com- 
stock about  Ithaca,  New  York,  '*among  scattered  trees  on  the  crests 
and  slopes  of  our  highest  hills."  In  the  West,  however,  Allen  found  it 
in  Iowa  "•common  in  grassy  groves"  and  "on  prairies,"  while  McNeill 
says  that  in  Illinois  it  "'is  very  frequently  found  along  roadsides  or  in 
pastures,"  and  in  Indiana  Blatchley  finds  it  "in  open  woods  and 
pastures."

This  group  is  composed  of  rather  heterogeneous  material  if  the  ma- 
cropterous  forms  alone  are  considered,  and  is  even  more  loosely  coin- 
l»acted  when  the  brachypterous  species  are  mingled  with  them.  In 
size  they  range  from  rather  small  to  medium.  A  single  species  is 
dimori)hic,  being  both  brachypterous  and  macropterous.

One  nnile,  three  females.  Georgia,  Morrison;  Smithville,  Xortl: 
Carolina,  November  22. 

It  seems  very  probable  that  this  species  is  the  Pizotettiv  zimmcrmanni 
of  Saussure,  described  from  the  female  only,  but  1  find  it  impossible  to 
deternnne  from  the  descrii>tion.  If  it  should  so  prove,  of  course  the 
name  has  priority  over  the  one  here  employed.

13.  ItrSTICUS  SERIES. 

This  is  a  tolerably  homogeneous  group  in  which  tiie  prozona  of  the 
male  varies  from  (juadrate  to  distinctly  longitudinal  and  in  which  the 
mesosternal  lobes  of  the  same  sex  are  se|)arated  by  an  interspace 
which  is  rarely  a  little  transverse,  usually  (juadrate  or  subquadrate, 
and  rarely  as  much  as  nearly  half  as  long  again  as  broad.  The  hind 
border  of  the  pronotum  is  usually  very  obtusangulate,  and  the  tegmina 
always  abbreviate,  usually  about  as  long  as  the  pronotum.  The 
hind  tibiae  are  usually  red,  rarely  pale  greenish,  with  usually  ten  to 
eleven  spines  in  the  outer  series,  but  sometimes  nine  or  twelve,  and  in 
one  case  only  seven  spines  may  be  found  in  th*^  female. 

The  male  abdomen  is  usually  more  or  less  clavate  and  recurved,  the 
supraanal  plate  triangular,  its  median  sulcus  inclosed  by  high  walls

developed  as  slijjht,  taperinj^  denticulations  only,  and  in  one  case  these 
disappear,  hut  sometimes  they  are  longer  so  as  to  be  nearly  or  quite  ii 
fourth  as  lon^  as  the  supraanal  plate;  the  <'erei  are  simple  blades  of 
moderate  breadth,  j^enerally  a  little  arcuate,  taperin^^  a  little  in  the 
]>ro\imab  subeipiid  in  the  <listal  half  and  rouiuled  apieally,  not  reach 
ing  the  tip  of  the  supraanal  plate;  the  sub<^enital  plate  is  small  and 
the  lateral  and  apical  marj;ins  usually  on  the  same  plane,  except  for  a 
slight  apical  elevation  or  anovulation  which  nmy  take  the  form  of  a 
tubercle,  but  in  one  species  this  also  is  wantinji. 

The  species,  mostly  (d  medium  or  sniall  size  and  seven  in  nund)er. 
have  a  tolerably  wide  ranjje  in  the  western  portion  of  the  continent, 
from  Washinjjton,  South  Dakota,  and  Michigan  to  southern  <'alifornia, 
Texas,  an<l  Mexico;  but  with  a  single  exception  (Montana),  the  sanu' 
ilistrict  does  not  sujiport  two  species.  One  species  is  found  about  and 
near  the  upper  Mississippi,  a  second  along  the  eastern  border  of  the 
Itocky  Mountains  from  Montana  to  New  Mexico,  a  third  in  Montana, 
a  fourth  in  Washington,  and  the  others  respectively  in  southern  Cali- 
fornia, Texas,  and  Mexico.

Patrin:  Texas.     (Mus.  Holm.) 

Stal  places  this  species  in  his  fourth  division  of  the  genus  Pezotrfti.v, 
which  he  regards  as  equivalent  to  Paroxya  8cudder,  and  which  be  detines 


NO.  1124.  REVISlnN  OF  THE  MKLAXOVLI^SCrDDEIL  241 


merely  in  terms  of  the  abdominal  api)eii(latfes  of  the  male:  it  is,  there- 
fore, not  equivalent  to  Paro.if/a  as  1  formerly  delined  it  and  as  I  here 
still  more  closely  distinguish  it  from  the  other  genera. 

14.  BORCKII  SERIES. 

A  homogeneous  group  in  which  the  prozona  of  tin'  male  is  <listinctly 
longitudinal  and  from  a  third  to  a  lialf  longer  than  the  metazona,  the 
posterior  margin  of  the  pionotum  being  subtruncate.  The  interspace 
between  the  mesosternal  lobes  in  the  same  sex  varies  from  a  little  longer 
than  broad  to  twice  as  long  as  broad.  The  antennae  vary  considerably 
in  length,  but  generally  <lirt*er  but  little  between  the  two  sexes.  There 
is  also  little  diversity  between  the  sexes  in  the  jn'oniinence  of  the  eyes. 
The  hind  tibiae  are  dark  blue,  sometimes  purplish,  and  have  nine  to 
twelve  spines  in  the  outer  series. 

The  supraanal  plate  is  triangular  with  acutangulate  or  rectangulate 
apex;  the  furcula  is  reduced  to  mere  projecting  points;  the  cerci  are 
broad  and  swollen  at  the  base,  taper  rapidly,  and  terminate  in  a  slen- 
der, })roduced,  more  or  less  curling  linger;  the  supraanal  plate  is  either 
very  narrow  as  compared  to  its  length  and  then  deeply  hollowed  api(; 
ally,  with  a  strongly  sinuate  lateral  margin,  or  it  is  only  a  little  longer 
than  broad  with  a  nearly  straight  margin,  the  apical  margin  always 
entire. 

There  are  six  sjiecies,  ranging  from  rather  small  to  a  little  above  the 
medium  size,  and  they  are  mainly  confined  to  the  J*aciHc  coast  from 
Washington  to  California.  But  one  of  the  species  occurs  also  as  far 
inland  as  Idaho  and  Wyoming,  and  another  is  known  from  San  Luis 
Totofei,  Mexico.

considerably  broader  tegmina  than  any  of  the  others  and  hardly  any

15.  PFER  SERIES. 

In  the  species  of  this  small  group,  the  prozona  of  the  male  (and 
generally  of  the  female)  is  longitudinal  and  nearly  twice  as  long  as 
the  metazona,  with  its  truncate  or  feebly  produced  !dnd  nargin;  the 
median  caiina  is  similar  throughout.  The  interspace  between  the 
mesosternal  lobes  in  the  same  sex  is  slightly  or  nundi  longer  than 
broad.  The  nnile  antennae  are  long  and  considerably  nger  ])ropGr- 
tionately  than  those  of  the  female.  The  tegnr'  are  abbreviate,  of 
about  the  length  of  the  i)ronotum,  obovate  and  apically  rounded. 
The  hind  tibiae  are  prevailingly  glaucous,  tiie  spines  ten  to  eleven, 
rarely  nine,  in  number  in  the  outer  series. 

The  supraanal  ])late  of  the  male  is  triangular  or  hastate,  the  surface 
subtectate  with  a  deep  median  sulcus;  the  furcula  is  variable  in  length, 
either  reduced  to  mere  denticulations  or  developed  as  parallel  spines 
nearly  a  third  as  long  as  the  supraanal  plate;  the  cerci  are  small  and 
styliform  with  slight  concavity  of  the  upper  margin,  acuminate  and 
nnich  shorter  than  the  supraanal  plate;  the  subgenital  idate  varies 
considerably  but  is  rather  full,  and  the  apical  margin  entire. 

Two  species  are  known, one  very  small  from  Florida,  the  other  rather 
large  from  Texas,  and  they  are  bronght  together  in  one  group  princi 
pally  fiom  their  simple  styliform  cerci.

This  is  the  smallest  known  spe(;ies  of  Melano^lun, 

K).  INOUNATLS  SKKIKS. 

The  prozona  of  the  male  is  here  distinctly  longitudinal,  and  the 
interspace  between  the  mesosternal  lobes  in  the  same  sex  (piadrate, 
or  feebly  longitudinal.  The  hind  margin  of  the  pronotum  is  either 
truncate  or  very  broadly  obtusangulate.  The  tegmina  are  abbreviate 
and  nearly  as  long  as  if  not  somewhat  longer  than  the  pronotum,  some- 
times rounded  and  sometimes  subacuminate  ajucally.  The  hind  tiojae 
are  generally  green,  and  the  species  vary  much  in  the  number  of  spines 
ill  the  outer  series,  ranging  from  nine  to  fifteen. 

The  supraanal  plate  is  triangular  and  generally  rather  tiat,  the  lateral 
margins  hardly  elevated;  the  furcula  may  be  either  reduced  to  slight 
jirominences  or  produced  as  delicate  spines  crossing  the  basal  fourth  of 
tlie  supraanal  plate;  the  cerci  again  vary  considerably,  being  either 
stout,  strongly  constricted  in  the  middle  and  widely  expanded  apically, 
or  tapering  to  a  half  or  two  thirds  the  basal  breadth  and  then  forming 
a  relatively  slender,  slightly  decurved,  compressed  tinger;  the  subgeni- 
tal plate  is  narrower,  generally  considerably  narrower,  than  long,  with 
aiigulate,  slightly  elevated  and  tuberculate  extremity. 

The  species  are  rather  slender,  of  about  medium  size,  and  are  three 
in  number.  One  occurs  in  Mexico,  a  second  in  North  Carolina,  and  the 
third  in  Illinois  and  Indiana.

Twelve  males,  13  females.  Illinois,  Uhler;  Hock  Island,  Illinois,

Illinois,  .lune  20,  J.  A.Allen;  Riviere  de  Pare,  June  14,  L.  Bruuer: 
Vigo  County,  Indiana,  May  25,  June  8, 11,  lUatchley  (W.  S.  Blatchley: 
A.  P.  Morse).  A  specimen  in  the  U.  S.  National  Museum  from  .Montana 
perhaps  belongs  here. 

It  has  also  been  reported  by  McNeill  from  McLean  County,  Illinois, 
and  Monroe  County,  Indiana. 

This  species  is  remarkable  for  the  length  of  the  antennae.  It  matures 
very  early,  McNeill  having  taken  it  as  early  as  June  5  in  Illinois,  wherr 
he  thinks  it  is  the  first  Orthopteron  to  mature  from  eggs  of  the  same 
season.  Blatchley  records  it  in  Indiana  even  as  early  as  May  11. 
McNeill  says  "it  is  by  no  means  common,  .  .  .  being  restricted  to 
a  few  localities  [about  Moline].  It  shows  a  decided  preference  for  the 
sides  o''  open,  grassy  ravines."'  One  specimen  before  me  is  marked  by 
Blatchley  as  found  in  woods. 

The  species  has  never  before  been  described,  but  has  been  mentioned 
by  Walsh's  names  in  several  publications;  the  specific  name '' viridu 
lus''  used  on  one  or  two  occasions  was  a  misreading  of  Walsh's  name 
''viridicrus,"  and  probably  originally  due  to  bad  chirography  on  my 
part.

17.  FASClxVTlS  SKKIES. 

This  <;roup  is  not  very  homo<ieneous,  comprisin;.!-  forms  of  conisider- 
able  dilVerence  in  ai)pearauce  and  structure,  but  which  have  a  numl»er 
of  important  ]M)ints  in  common.  It  is  coinpose«l  in  i»art  of  brachyi>ter- 
ous  and  in  part  of  nuiv*ropterous  forms.  One  sj)ec'ies  is  dimorphic  in 
this  respect,  and  the  others,  whether  macroi)terous  (one  onlyj  or 
brarhyi>terous  (six  in  number),  are  excejJtionally  sliort-winj:ed  or 
exceptionally  lon<i-winf?ed  for  their  type.  The  antennae  are  very  vari- 
able in  len;:th.  beinj;'  sometimes  (juite  similar,  sometinu's  (juite  dissimi- 
lar, in  the  two  sexes  aiul  varying  in  the  male  from  three-tifths  as  lon^ 
as  the  hind  femora  to  eipuil  their  length,  an<l  in  the  female  from  one- 
half  to  four-tifths  the  length  of  the  hin«l  femora.  In  size  they  range 
from  very  small  to  a  little  above  the  medium. 

The  prozona  of  the  male  varies  from  (piadrate  to  longitudinal  in 
both  brachypterous  and  nmcropterous  forms.  The  intersjtace  between 
the  mesosternal  lobes  in  the  same  sex  is  also  very  variable  in  each  set 
of  forms,  and  in  both  together  ranges  from  a  little  tiansverse  to  twice 
as  long  as  broad.  The  tegmina  in  the  brachypterous  forms  are  usually 
comparable  with  the  length  of  the  ])ronotum  and  are  well  rounded,  but 
in  the  dimor])hic  form  they  are  api  *ally  subacuminate  and  twice  as  long 
as  the  proncttum  (as  in  one  of  the  brachypterous  forms)  or  far  surpass 
the  hiiul  femora  and  are  broad  and  well  rounded  apically;  while  in  the 
single  macropterous  form  they  barely  reach  the  tip  of  the  hind  femora. 
Tl'.e  hind  tibiae  are  likewise  very  variable  in  color,  sometimes  within  the 
species,  and  have  from  nine  to  twelve,  usually  eleven,  spines  in  the 
outer  series. 

The  supraanal  plate  is  generally  rather  long  triangular,  and  rather 
flat,  with  but  feebly  elevated  margins,  except  in  one  instance,  where  it 
is  strongly  comj>;.  :^t;d  apically.  The  furcula  is  usually  very  feebly 
developed,  but  th/ve  species  have  slender  fingers  extending  some  dis- 
tance over  t'ue  supraanal  plate.  The  cerci  are  rather  large,  compressc<]. 
generally  incurved  laminae,  generally  of  considerable  breadth,  but  in 
one  instance  exceptionally  slender,  generally  more  or  less  constrict(  <l 
mesially,  in  two  species  greatly,  and,  with  a  single  exception,  enlarged 
again  ai)ically,  rounded  and  not  acumiiuite  (in  one  species  emarginatoi 
at  tip.  The  snbgenital  plate  again  varies  much,  but  is  always  lon.i^cr 
than  broad,  generally  moderately  broad  and  nearly  equal  and  usually 
a  little  elevated  apically.  the  apical  margin  always  entire. 

The  eight  species  have  as  little  geogTai>hical  as  structural  relation. 
One  is  known  only  from  the  extreme  north  in  Labrador  and  Cireeulaml:

The  most  aberrant  nuMuber  of  the  series  is  M.  hvrmlis.     None  of 
them  are  likely  to  be  confouiuled.

Blatchley  also  reports  it  from  Moiuoe  County,  Indiana,  and  if  Saus- 
sure's  species  is  the  same  it  is  also  found  in  Carolina.  Blatchley  says 
'•it  reaches  maturity  about  September  1,  and  frequents  for  the  most 
part  high,  dry,  open  woods,  especially  those  in  which  beech  and  oak 
trees  predominate  ...  In  late  October,  if  the  season  is  dry,  it  is 
often  found  .  .  .  among  the  reeds  and  tall  rank  grasses  near  the 
l>onler  of  nnirshes."

It  tlieretore  occurs  in  a  broad  belt  along  our  northern  border  from  the

As  seen  in  the  above  description,  the  species  occurs  in  two  forms,  a 
moderately  short-winged  form,  to  which  the  name  .1/.,/".  curtua  (J?late 
XVI II.  figs.  2-3)  maybe  given  (it  was  once  described  as  curtHti)',  and 
a  very  long  and  broad  winged  form,  which  may  be  called  M.f.  rolaticiLs 
(Plates  I,  tig.  c;  XVIII,  tig.  4).  The  latter  is  known  only  from  Michi-

Fieber  also  reports  it  from  (ireenhnnl  and  Xorth  Cape,  Norway.  It  is, 
however,  not  included  in  the  Kuropean  fauna  either  by  II.  Fischer  or  by 
IJiumier  von  Wattenwyl;  yet  Fieber  credits  specimens  to  the  Vienna

As  MvlnuttjtJuH  and  Vinlixmti  are  the  genera  of  Melanopli  most  abun 
dant  in  forms  ami  most  widely  spread,  the  former  being  especially  true 
of  MvlmtopUiH^  and  as  the  present  fcuin  is  the  species  of  Mrlanoithis 
most  nearly  allied  to  Podisma,  and,  like  most  of  the  species  of  the 
latter  genus,  is  peculiar  to  high  latitiules  or  altitudes,  it  seems  proper 
to  regard  M.  hortalis  as  an  archaic  form.  perha])s  more  nearly  than  any 
other  resembling  the  original  form  frou)  which  the  Melanopli  as  a  whole 
have  descended. 

Mr.  Samuel  Ilenshaw  recently  compared  for  me  a  female  specimen  of 
this  species  from  Labrador  with  Walker's  type  of  Calopienus  arrtictis 
in  the  British  Museum.  He  found  tli^m  to  agree  except  in  length  ot 
wings,  which  in  Walker's  specimen,  a  uni(|ue,  "extend  sligiitly  beyond 
the  abdomen  ;"  the  prosternal  spine  was  the  same.  I  have  accordingly 
introduced  it  in  the  synonymy  with  a  question  mark;  if  it  belongs  her*' 
the  range  of  the  species  should  be  extended  to  whatever  point  it  Uiay 
have  been  in  ••  Arctic  America"  that  Doctor  llie  collec^ted  his  specimei. 

The  specimens  which  1  have  seen  were  taken  by  Mr.  Sornbergcr 
August  15-U»  at  ths  Es(|uimau\  village  of  Bama.  He  tells  me  that 
they  were  all  taken  on  the  banks  of  a  mountain  brook  fed  by  the  nudt- 
ing  snows  of  the  sutnmit  near  by.  They  were  most  abundant  where 
tlie  vegetation  was  most  luxuriant  at  the  bo:dersof  the  brook;  noiu' 
were  found  below  an  elevation  of  200  feet  no)-  above  l.oOO  feet,  at  whidi 
altitude  herbaceous  ]»lants  became  few  and  scattering.  Mr.  Sornbcr- 
ger  can  not  say  upon  what  it  fed.  but  it  was  not  found  on  any  of 
the  shrubby  i>lanls  common  there — Betula.  Vaccinium,  Ledum.  Salix. 
Kmiietrum,  etc.,  though  he  thinks  he  saw  it  on  some  of  the  Cyperaceac 

IS.  ALLENI   SERIES. 

In  this  sm.iU  series  the  prozona  of  the  male  is  slightly  longitudinal, 
and  the  interspace  between  the  mesosternal  lobes  in  the  same  sex  only 
a  little  longer  than  broad.  The  anteniuie  are  very  long.  The  tegmina 
are  always  abbreviate,  but  vary  considerably,  being  either  ellipti<al.

The  supraanal  plate  is  triaiifrular,  with  raised  niar«4:ins:  the  fiinula 
consists  of  a  pair  of  slight  and  distant  or  very  distant  jH-ojeetions;  thei

10.  FEMUIMJUBRUM  SElilES. 

This  is  a  dominant  and  homogeneous  group  of  medium  or  ratl'er  small - 
sized  species,  in  which  the  male  prozona  varies  from  slightly  transverse 
to  slightly  longitudinal,  and  the  interspace  between  the  mesosternal 
lobes  in  the  same  sex  is  as  in  the  spretus  series.  The  tegmina  are 
always  fully  developed  or  a  little  abbreviated  (so  as  to  fall  a  little 
short  of  the  tip  of  the  hind  femora),  immaculate  or  slightly  maculate 
along  the  middle  line.  The  hind  tibiae  are  normally  red  and  have  ten 
ti>  fourteen  spines  in  the  outer  series. 

The  supraanal  plate  is  clyj^eate,  longer  than  broad  and  mesially  con- 
st licted.  The  furcula  consists  of  a  pair  of  parallel  or  nearly  parallel, 
long  or  moderately  long,  generally  separated,  slender,  tapering,  sub-

laminae,  the  apical  half  generally  about  half  as  broad  as  the  base, 
arcuate  and  with  the  upper  inner  portion  of  the  tip  produced.  The 
subgeuital  plate  is  peculiar  for  beinj;  very  broad  at  base  and  narrowing 
so  as  to  be  at  apex  only  about  half  as  broad  as  at  base  (which  does  not 
show  in  the  tlgures),  the  wliole  lower  margin  nearly  straight  while  the 
u})per  is  sinuous,  the  apical  margin  not  elevated,  entire  (in  one  species 
very  broadly  and  shallowly  emarginate,  or  rather  laterally  tuberculate) 
and,  as  viewed  above,  broadly  rounded. 

The  species,  five  m  number,  are  spread  all  over  the  continent  from 
Atlantic  to  Pacific,  from  central  Labratlor  ^o  central  Florida,  and  from 
central  Alaska,  the  ]\rackenzie  River  and  Hudson  Bay  to  Texas  and 
central  Mexico;  they  also  extend  to  high  altitudes  above  the  forest  line. 
No  other  series  of  ]\Ielanoplus  has  quite  so  wide  an  area  of  distribution, 
the  bivittatus  series,  however,  approaching  it  closely.

costa  somewhat  prominent  above,  slightly  contracted  between  the 
antennae,  otherwise  subequal  and  as  wide  as  'ihe  interspace  between 
the  eyes  hardly  reaching  the  clypeus,  feebly  sulcate  at  and  below  tlie 
ocellus,  biseriately  punctate  throughout;  eyes  moderately  large,  not 
very  prominent,  distinctly  longer,  especially  in  the  female,  than  the 
intraocular  portion  of  the  genae;  antennae  more  or  less  ferruginous, 
apically  infuscated.  less  than  three-fourths  (male)  or  hardly  more  than 
one-half  (female)  as  long  as  the  hind  femora.  Prouotum  subequal,  very 
feebly  and  uniforndy  expanding  i)osteriorly,  especially  in  the  female, 
the  disk  dark  fusco-olivaceous,  with  a  slender,  median,  flavous  stri[)e

f^carcely  or  not  longer  than  the  closely  punctate  nietazoua.  Prosternal 
sjiine  moderately  long,  erect,  cylindrical,  in  the  fe'^.ale  slightly  appressed, 
bhmt;  interspace  between  mesosternal  lobes  fully  half  as  long  again 
as  broad  (male)  or  feebly  transverse  (female).  Tegmina  generally  sur- 
passing a  little  the  hind  femora,  of  moderate  breadth,  distinctly  tapering, 
olivaceo-fuscous,  immaculate  or  with  a  feeble  line  of  minute  maculations 
along  the  discoidal  area;  wings  hyaline,  glistening  and  iridescent,  with 
pale  fuscous  veins  darker  next  the  apex.  Fore  and  middle  femora 
scarcely  tumid  in  the  male;  hind  femora  blackish  olivaceous  on  the 
outer  face  excepting  sometimes  on  the  lower  margin,  elsewhere  flavous 
or  luteo-flav(ms,with  two  broad  blackish  olivaceous  maculations  above, 
especially  on  the  inner  side;  hind  tibiae  feebly  valgate,  red,  the  spines 
black  excepting  at  base,  eleven  to  thirteen  in  number  in  the  outer 
series.  Extremity  of  male  abdomen  considerably  clavate,  somewhat 
recurved,  the  supraanal  plate  subclypeate  but  mesially  contracted, 
apically  rectangulate,  the  margins  considerably  elevated,  forming 
deep  valleys  between  them  and  the  opposite  curved  ridges  border- 
ing the  median  sulcus;  the  latter  is  deep,  gradually  contracts  toward 
the  middle  and  then  rapidly  expands  and  shallows  (in  the  specimen 
chosen  for  illustration  the  apical  portion  is  concealed);  furcula  consist- 
ing of  a  pair  of  basally  adjacent,  apically  tapering,  parallel,  acuminate 
lingers,  nearly  half  as  long  as  the  supraanal  plate,  lying  in  the  valleys 
of  the  same;  cerci  subfalciform  lamellae,  which  taper  rapidly  in  the 
basal  half  and  beyond  are  less  than  half  as  broad,  slightly  incurved 
and  upcurved,  apically  tapering  by  the  curve  of  the  lower  margin,  the 
tip  blunt  and  falling  short  of  the  extremity  of  the  supraanal  plate; 
subgenital  plate  broad  at  base,  narrowing  rapidly,  the  extremity  hardly 
more  than  half  as  broad  as  the  base,  the  lateral  margins  strongly  arcu- 
ate, the  apical  margin  even,  entire,  well  rounded. 

Length  of  body,  male  20  mm.,  female  25  mm. ;  antennae,  male  S..'«  mm., 
female  6.75  mm.;  tegmina,  male  17  mm.,  female  17.5  mm.;  hind  femora, 
male  12  mm.,  female  13.25  mm.

and  it  has  since  been  recorded  by  Bruner  from  Canyon  City,  Fremont 
bounty,  Colorado,  and  the  plains  of  Wyoming. 

This  species,  especially  in  life,  is  strikingly  different  from  tne  next 
two  in  coloring,  though  the  male  abdominal  appendages  are  exceedingly 
t^iniilar.  According  to  Bruner.  it  is  more  clumsy  in  its  movements  than

ruginous or  luteo-ferruginous,  often  a  little  infuscated  apicallj ,  about 
four-fifths  (male)  or  three-fifths  (female)  as  long  as  the  hind  femora. 
Pronotum  feebly  and  rather  regularly  expanding  posteriorly,  the  disk 
faintly  convex  and  passing  by  a  well-rounded  shoulder  (somewhat 
abruptly  on  the  metazona)  into  the  anteriorly  tumid  vertical  lateral 
lobes,  the  disk  generally  darker  than  the  lower  portion  of  the  lat-

generally  confined  to  the  upper  half,  and  above  generally  concentrated 
in  two  fasciae,  which  sometimes  extend  partly  in  an  oblique  direction 
on  the  outer  face,  but  generally  in  a  very  obscure  fashion,  if  at  .ill, 
while  the  whole  under  surface  and  at  least  the  basal  half  of  the  inner 
surface  is  more  or  less  impure  tiavous,  sometimes  deejiening,  especially 
beneath,  to  ferruginous  or  even  carmine:  hind  tibiae  normally  red, 
sometimes  with  a  slight  fuscous  patellar  spot,  occasionally  more  or 
less  tinged  with  yellowish,  very  rarely  pale  green  with  a  yellowish

pressed laminae,  tapering  considerably  and  rather  rapidlj'  from  base  to 
middle,  beyond  that  subequal  but  apically  very  obliquely  truncate,  so 
that  the  upper  angle  is  cotisiderably  produced  but  blunt,  the  whole

ginia (Glover) ;  Kentucky  (Glover,  Garmau ) ;  Tennessee  (De  Haan),  and 
Wyoming  (Thomas).  Si)ecimens  from  Florida  which  I  formerly  referred 
to  this  species  probably  belong  to  the  next. 

It  t)ierefore  appears  to  inhabit  the  entire  United  States  and  tht  set- 
tled parts  of  Canada,  excepting  only  Alaska  and  also  the  southeastern 
United  States  (where  it  is  replaced  by  the  next  species),  and  occurs 
south  of  our  border  as  far  as  central  Mexico. 

The  species  described  by  me  as  M.  interior  vf an,  based  upon  specimens 
from  Utah  and  other  parts  of  the  interior  of  the  western  country,  which 
seem  to  differ  from  those  found  elsewhere  in  having  cerci  which  taper 
more  gradually  and  show  less  contrast  in  the  width  of  the  basal  and 
apical  halves,  and  at  tip  are  blunter  and  less  manifestly  truncate,  in 
which  also  tlie  forks  of  the  furcula  are  relatively  longer  and  more 
strictly  parallel,  the  tegmina  rather  shorter  and  generally  lacking  any 
maculatiou  v  tmte\er;  the  prosternal  spine  also  is  more  frequently  com- 
pressed before  the  tumid  tip;  but  on  comparing  a  large  series  of  speci- 
mens from  these  western  regions  I  tind  it  impossible  to  draw  any  line 
of  demarcation,  some  specimens  having  some  but  not  other  of  these 
characteristics,  so  that  I  can  only  regard  the  species  as  in  a  state  of 
tiux  in  this  region,  preparing,  as  it  were,  to  divide  into  distinct  races 
not  yet  clearly  enough  defined  to  distinguish  them. 

'  The  first  three  references  are  doubtful ;  they  probaMy  belong  to  M.  extremum.

jdaces;  but  as  thej'  are  unitc<l  with  the  tyi)e  hy  comph'te  series  of 
intergrades.  1  anj  forced  to  conchule  them  to  be  only  extreme  color- 
ational  va.iations,  whi<"h  can  not  be  di«rnitied  even  as  races. 

Specimens  with  jjrcen  or  greenish  hind  tibiae  have  b«>pti  seen  by  me 
from  the  aljjine  region  of  the  White  Mountains,  New  Hampshire,  ('ai)e 
Cod,  Nantucket,  (Ireat  Island,  and  Cambridge,  Massachusetts,  Ctah, 
Carrizo  Springs,  Texas,  and  (^)uerataro,  Mexico, 

There  can  be  no  doubt  that  this  is  the  true  fcmurruhnim  of  De  (leer, 
since  Stal  has  dcsi-ribed  the  anal  cerci  of  the  niah'  from  the  type  of 
De  Geer's  description,  and  I  myself  made  direct  comparisons  with 
varied  material  when  in  Sweden,  nearly  thirty  years  ago. 

In  llayden's  report  on  the  survey  of  Nebraska  (1872),  I  collected 
several  accounts,  printeil  and  unpublished,  of  the  injury  to  crops  attrib- 
uted to  this  s])ecies  in  the  eastern  Cnited  States.  As  up  to  that  time 
]\1.  athtnis  had  not  been  distinguished  from  M./viuur  ruhrum,  it  is  pos- 
sible, and  I  am  now  inclined  to  think  it  probable,  that  all  the  serious 
injury  d(me  to  crops  in  the  East  is  done  by  M.  atlonis;  for  although 
almost  everywhere  less  common  than  M .  femur-rnhrum ^  M.  athinls  has 
been  shown  to  have  the  cai)acity  for  immense  multijdication,  and  has 
been  directly  i)roved  to  be  the  culprit  in  some  instances;  as  it  is  also 
much  more  closelj'  and  indeed  very  closely  related  to  the  destructive 
locust  of  the  West,  .1/.  aprctux,  it  is  far  more  likely  to  have  been  the 
actual  pest  in  all  the  records  of  the  past.  At  least  until  direc*:  provable 
charges  are  made  against  it,  .1/.  Jemurrubrum  should  be  looked  upon 
as  less  injurious  than  M.  atlanis;  it  is  especially  doubtful  whether  it 
ever  migrates  in  aerial  swarms;  as  a  general  rule  the  tegmina  and 
wings  are  longer  in  ^1/.  athniits  than  in  M.fi'mur-rubnnn^  though  both 
species  vary  considerably  and  intergrade  in  that  particular.  From 
measurements  made  on  Mis-souri  specimens,  IJiley  found  that  the  teg- 
mina in  the  present  species  extended  beyond  the  abdomen  as  follows: 
In  28  males,  0-2  mm.,  average,  0.8  mm.;  in  54  females,  0-3  mm.,  aver- 
age, 1.1  mm. 

Bruner  excellently  expresses  the  fact  when  he  says  that  the  imme- 
diate distribution  of  this  insect  "appears  to  be  controUetl  altogether  by 
climatic  conditions,  the  chief  of  which  is  the  i)reseuce  of  a  certain 
amount  of  humidity.  .  .  .  It  is  a  frequenter  of  low  grounds,  culti- 
vated fields,  shady  margins  of  Avoods,  etc.,  where  vegetation  is  rank 
and  tender.''  It  is  rarely  found  upon  dry  hillsides  when  meadows  close 
at  hand  may  swarm  with  them,  while  the  opposite  is  true  of  other 
species,  J/,  coll  inns  for  instance;  yet  such  specimens  as  do  so  occur  will 
be  found  to  differ  from  those  inhabiting  more  favored  localities,  in  being 
lighter  colored  and  more  uniformly  grayish  in  tone,  with  slighter  con- 
trasts; those  from  drier  stations  appear  also  to  have  on  the  average 
rather  shorter  wings.

in  New  Kngland  late  in  .Inly.  Acconlinjj  to  L'iley.  the  v^^a  are  not 
laitl  iu  a  single  mass,  but  at  intervals  in  several;  he  has  twice  obtained 
four  successive  pods  from  a  sinj;le  female,  covering  a  perio*!  of  nearly 
two  months  and  containing  eggs  amounting  in  nil  t«>  from  ninety-six  to 
one  hundred  and  ten.  The  eggs  have  a  quadrilinear  arrangement  iu 
the  pods. 

At  Andover,  Massachusetts,  on  October  "»  many  years  ago  I  observed 
a  pair  of  this  species,  male  and  female,  near  together  alternately  sig- 
naling to  each  other  with  a  slight  <|uick  niovenuMit  of  the  hind  legs 
ui)on  the  tegmina,  as  if  stridulating.  I  made  no  note  of  whether  any 
sound  was  actually  produced  and  do  not  now  recall  any. 

Many  interesting  notes  regarding  this  species  will  be  found  in  the 
first  report  of  the  United  States  Entomological  Commission.

Of  medium  size,  closely  resembling  the  preceding  species  in  colora- 
tion, but  generally  of  a  somewhat  lighter  tint.  Head  a  little  promi- 
nent, tiavo-testaceous,  generally  more  or  less  infuscated  above,  with

This  species  takes  in  our  Southern  Atlantic  States  the  place  of  M. 
femur-ruhnim,  which  it  closely  resembles;  it  is  most  quickly  distin- 
guished from  it  by  the  form  and  sculpture  of  the  supraanal  i)late  and 
the  much  greater  length  of  the  furcula.

It  has  also  been  reported  from  (Quebec  (Provancher,  Scudder;  Dodge 
County,  Nebraska  (Dodge), and  the  Mackenzie  River,  British  America, 
at  latitude  05°  (KirLy);  the  last,  however,  is  uncertain,  dependingon  the 
determination  of  Kiiby's  species.  It  probably  occurs  throughout  the 
larger  part  ol  Canada  and  the  northernmost  United  States. 

As  indicated  in  the  deseiiption,  this  insect  appears  in  two  forms:  a 
short  winged  (J/.  e.jiiniuH),  in  which  the  tegmina  at  rest  do  not  reach 
the  tips  of  the  hind  i*emora:  and  a  long-winged  (for  which  1  propose 
the  name  M.  e.  ncandens),  in  whu;h  Ihey  surpass  them,  generally  con- 
siderably. The  latter  has  also  a  slightly  slenderer  body,  though  the 
difference  is  not  marked.  It  appeals  to  affect  high  latitudes  and  alti- 
tudes, being  found  in  all  the  localities  in  the  high  north  where  Kennicott 
collected, on  the  Big  Horn  Mountains  in  W^yoming.  and  on  the  summits 
of  Greylock  in  Massachusetts,  and  the  White  Mountains  in  New  Hamp- 
shire, in  all  of  which  (unless  in  Wyoming,  wlir:ice  I  have  only  seen  two 
specimens)  it  is  the  prevailing  or  exclusive  form.  The  short-winged 
form,  however,  occurs  in  all  these  places  excepting  the  Aljnne  region  of 
the  White  Mountains,  where  it  has  not  been  taken ;  and  the  long  winged 
occurs  also  at  lower  levels  in  New  England,  as  at  North  Conway,  New 
Hampshire,  Jay  and  Montgomery,  Vermont,  and  Winchendon,  Massa- 
chusetts, but  it  is  only  found  in  these  places  exceptionally,  to  judge 
bom  the  specimens  seen.  The  two  specimens  from  the  Big  Horn 
Mountains,  the  male  scandens^  the  female  Junius,  are  of  exceptional 
size,  and  Arctic  American  specimens  are  also  distinctly  larger  thaiL 
those  from  New  England  or  Nebraska.

It  will  probably  be  iini)ossible  ever  to  detenniiie  detinitely  Kirby's 
Loritata  leucofftoma,  as  the  description  is  altogether  inadequate  and  the 
British  Museuiu  does  not  contain  the  type;  at  least  I  could  not  find  it 
by  special  search  for  it  in  1865,  and  it  is  not  mentioned  in  Walker's 
catalofjfues;  Walker,  foHowing  mj'  earlier  but  probably  wrong  determi- 
nation, i)laced  it  as  a  synonym  of  M.  biviitatuSj  but  none  of  his  sj)eci- 
mens  included  Kirby's.  ^ 

Mr.  Samuel  Ilenshaw,  during  a  recent  visit  to  the  British  Museum, 
examined  the  types  of  Walker's  (JaloptenuH  ej-t  rem  its  and  found  tiiem  to 
agree  with  si)ecimens  of  the  present  species  coming  from  Kennicott's 
collection  on  the  upper  Mackenzie,  which  he  took  with  him;  they 
differed  "only  in  having  slightly  shorter  wings,"  in  which  respect 
Walker's  specimens  agree  with  others  of  Kennicott's  collection  belonging 
to  this  species.  .

In  this  more  than  usually  homogeneous  group,  the  male  prozona  is 
quadrate  or  slightly  longitudinal,  and  the  interspace  between  the 
mesosternal  lobes  of  the  same  sex  varies  from  a  little  longer  than  broad 
to  twice  as  long  as  broad.  The  tegmina  are  always  fully  developed, 
surpassing  somewhat  the  hind  femora,  and  at  most  are  feebly  maculate, 
the  flecking  not  always  confined  closely  to  the  discoidal  area.  The 
liind  tibiae  are  blue  or  green  (in  one  instance  apparently  reddish  yellow) 
and  have  ten  to  twelve  spines  in  the  outer  series.

The  supraaual  plate  is  generally  rather  simple,  triaiijiular  with 
convex  sides  and  a  generally  produced  apex,  but  is  sometimes  strongly 
and  abruptly  compressed  apically.  The  tiircula  is  develojied  to  an 
extreme  as  a  pair  of  parallel,  flattened,  pointed  plates,  usually  more 
than  half  as  h)ng  as  the  supraanal  ])late.  Tlie  cerci  are  rather  slender 
or  only  moderately  broad,  apically  spatulate  or  subspatulate,  incurved 
or  inbent,  of  variable  length  relative  to  tiie  supraanal  plate.  The  sub- 
genitrl  plate  is  moderately  broad  apically,  but  distinctly  narrower 
than  long,  the  apical  margin  entire  and  not  elevated,  or  only  slightly 
elevated.  v 

The  species,  sis  in  number,  are  of  medium  or  slightly  above  the 
medium  size  and  with  the  exception  of  the  typical  spe<;ies  are  found 
only  in  the  extreme  Southwestern  States — Southern  California,  Arizona,

extends  the  range  on  the  north  to  Washington,  Idaho,  and  Wyoming, 
and  eastward  to  Louisiana  and  western  Nebraska.  It  is  a  western 
type.

M.  cinercus,  and  may  i)rove  to  be  a  variety  of  it,  found  in  different  sta- 
tions. It  wholly  lacks,  however,  the  cinereous  si)eckliiig  so  characteris- 
tic of  typical  exam])les  of  the  latter  species,  with  the  rusty  hue  of  the 
pnmotum. 

Some  individuals  are  much  smaller  than,  hardly  more  than  half  as 
large  as,  others;  the  measurements  are  taken  from  the  larger  and  appar- 
ently commoner  forms.  /      .

and  the  San  .loatpiin  Vjdley,  California  (Coquillett). 

1  have  found  this  insect  only  upon  the  sajje  brush  (Artemisia),  and  so 
completely  do  its  ffiay  and  rusty  colors  harmonize  with  its  surround- 
ings that  it  is  extremely  dillicult  to  detect  when  at  rest.  This  has 
also  been  noticed  by  liruner,  who  remarks  that  the  resemblance  extends 
to  the  earlier  stajres  of  the  insect. 

Coquillett  remarks  upon  the  ease  of  its  tiijjht,  describing  it  as  in  a 
straight  line,  for  a  distance  of  from  5  to  20  feet  from  the  ground.  He 
found  it  devouring  the  ripe  kernels  of  rye  in  Calitbrnia,  and  Riley 
reports  it  as  injuring  cotton  in  Louisiana.  Coquillett  regards  it  as  a 
migrating  species,  but  his  specitic  statements  refer  only  to  short  flights 
from  the  fields  to  the  tree  tops  or  the  reverse,  fifty  to  one  hundred 
yards  being  the  usual  distance.  In  the  San  Joaquin  Valley  he  found 
specimens  pairing  at  the  last  of  July.

This  species  is  rather  rloaely  allied  to  the  last,  M.  complanatijus,  i)ut 
is  easily  distinguished  from  it  by  its  less  stron^jly  compressed  hind 
femora  with  their  bifasciate  markings.  The  dit^erences  in  the  abdom- 
inal appenda^a»8  are  slight,  but  are  found  at  every  point. 

21.  ANGUSTIPENNIS  SEIUES. 

A  very  homofjeiieous  group  (and  one  very  closely  allied  to  the  i)re- 
ceding),  in  which  the  prozona  of  the  male  is  variable,  and  the  interval 
between  the  mesosternal  lobes  in  the  same  sex  varies  tVom  a  little 
longer  to  several  times  longer  than  broad.  The  tegmiiia  are  always 
fully  develoi)ed  ami  reach  or  somewhat  surpass  the  tips  of  the  hind 
femora.  The  hind  tibiae  are  red  or  glaucous  and  have  from  nine  to 
thirteen  spines  in  the  out-er  t^eries. 

The  supraanal  plate  is  long  and  rounded  triangular,  and  j»reapically 
contracted  somewhat  conspicuously.  The  furcula  consists  of  a  i»air  of 
slender,  tapering,  acuminate  lingers  of  considerable  length,  generally 
extending  over  a  third  of  the  supraanal  plate.  The  cerci  are  rather 
short  and  rather  slender,  incurved  or  inbent  ai)ically,  spatulate,  not 
nearly  re  'hing  the  tip  of  the  supraanal  plate.  The  subgenital  plate  is 
large,  fully  as  broad  as  long,  not  or  but  little  elevated  ai)ically  and 
there  usually  feebly  notched. 

The  species,  only  four  in  number,  are  of  medium  or  rather  small, 
occasionally  rather  large  size,  and  occur  from  Iowa  to  Utah,  and  from

Bruner  states  that  this  species  feeds  on  Artemivsia  and  ])refers  "  to 
jumj)  from  ])lant  to  plant  rather  than  to  alight  upon  the  ground.''  "  It 
occurs  both  on  high  and  low  lands,  but  appears  to  be  somewhat  partial 
to  old  breakings  and  well-fed  i)astures  of  many  j-ears'  use.'' 

I  suspect  that  the  insect  from  Minnesota,  described  by  Thomas'  as  a 
variety  of  CaJopienus  orcifleiitdlis,  may  belong  to  this  species.

Iliad  formerly  mistaken  this  species  for  Cal.  occidentalls  Thomas,  and 
distributed  specimens  under  that  name.  This  note  may  serve  to  correct 
the  error.  The  longer  furcula  serves  somewhat  readily  to  distinguish 
this  species  from  the  preceding,  smaller  and  less  heavily  maculate 
species.

This  is  a  group  in  which  the  prozona  of  the  male  is  usually  quadrate 
or  subquadrate,  and  the  interval  between  the  mesothoracic  h)bes  of  the 
same  sex  varies  from  quadrate  to  fully  twice  as  long  as  broad.  The 
prosternal  spine  is  usually  rather  short,  often  appressed.  The  tegmina 
are  always  fully  developed  and  reach  or  surpass  a  little  the  tips  of  the 
hind  femora;  the  hind  tibiae  are  generally  red,  sometimes  blue,  and 
have  nine  to  twelve  spines  in  the  outer  series.         - 

The  supraanal  plate  is  as  in  the  collinus  series.  The  furcula  is 
slightly  developed,  consisting  of  moderately  slender  denticu-lations,  not 
longer  than  the  last  dorsal  segment.  The  cerci  are  generally  moder- 
ately broad,  gently  si)atulate,  the  apical  portion  generally  inbent, 
sometimes  merely  incurved,  often  externally  sulcate.  The  subgenital 
plate  is  never  very  broad,  ordinarily  rather  narrow,  subecjual  or  apically 
narrowed,  the  a])ical  margin  neither  elevated  nor  x^rolonged,  and  gen- 
erally well  rounded  and  entire. 

The  five  species  are  of  rather  large  or  medium  size,  and  comprise 
two  tolerably  distinct  sets:  one,  of  two  species,  of  ordinary  form,  with 
short,  apically  truncate  cerci,  not  nearly  attaining  the  tip  of  the  supra- 
anal plate,  and  with  strongly  divergent  forks  to  the  furcula;  and  a 
second,  of  three  species,  of  very  robust  form,  cerci  which  though  short

It  has  also  been  reported  from  (lanlen  City,  Kansas  (Bruner),  Ke^Ljina, 
Assiniboia  (Caultield),  and  northern  Calitbrnia,  abundant  (Koebele). 

This  species  bears  a  close  general  leseiiiblance  to  M.  birittatux,  from 
which  it  is  nevertheless  very  distinct.  Bruner  says,  with  regard  to  it, 
that  *'it  never  leaves  the  open  country  for  tind)eied  or  low  localities 
where  the  vegetation  is  rank,"  as  that  and  other  species  do.  It  is  a 
prairie  species. 

Coekerell  has  given  the  variety  with  red  hind  tibiae  a  distinctive 
name.  1  have  seen  it  from  British  Columbia,  Washington,  Oregon, 
northern  California,  Idaho,  Montana,  Nebraska,  Kansns,Utah,  Nevada, 
Colorado,  and  New  Mexico.  It  appears  to  be  the  luevailing  if  not  exclu- 
sive form  in  some  northern  parts  of  its  range.  Specimens  before  me 
from  Wyoming,  Iowa,  and  Texas  have  blue  legs  only;  both  forms  occur 
in  Montana,  Nebraska,  Ctah,  and  Colorado. 

In  coloring  and  markings  it  is  one  of  the  most  variable  species  of 
Melanoplus  known  to  me,  but  1  have  been  unable  to  find  grounds  for 
specific  distinctions  between  the  various  forms,  which  seem  to  run  into 
each  other  completely.

more  or  less  blackened,  and  with  a  generally  <listinct  postocular  stripe; 
vertex  gently  tumid,  slightly  elevated  above  the  pronotum,  the  inter- 
space between  the  eyes  nearly  half  as  broad  again  (male)  or  twice  as

cate  (male),  about  as  long  as  the  intraocular  jjortion  of  the  geiiae; 
antennae  red,  sometimes  a  little  infuscated  apically,  somewhat  more  than 
fourtifths  (male)  or  than  two-thirds  (female)  as  long  as  the  hind  femora. 
Pronotum  stout,  distinctly  enlarging  posteriorly,  esi)ecially  in  the  female, 
more  or  less  and  irregularly  clouded  with  fuscous  on  the  disk,  ofteu 
with  a  ferruginous  tinge  especially  on  the  meta/ona,  the  lateral  carinae

by  lighter  tints;  disk  broadly  convex,  passing  into  the  subvertical 
lateraHobesby  a  rounded  shoulder  occasionally  forming  distinct  carinae; 
median  carina  distinct  on  the  metazona,  less  distinct  (female)  or  subob-

This  species  is  closely  related  to  the  preceding,  from  which  it  differs 
in  the  narrowness  of  the  subgenital  plate  of  the  male  an<l  the 
difference  in  the  interspace  between  the  mesosterual  lobes.  Its  general 
resemblance  is  very  close. 

23.  TEXANl  S  SERIES. 

In  this  not  altogether  homogeneous  group,  the  proz«)na  of  the  male 
is  longitudinal,  generally  distinctly  longitudinal,  and  tiie  intersi)ace 
betwee.  the  mesosterual  lobes  in  the  same  sex  is  almost,  or  fully,  or 
even  more  than,  twice  as  long  as  broad.  With  the  exception  of  the  first 
species,  the  hind  margin  of  the  pronotum  is  obtusangulate.  The 
antennae  are  variable.  The  tegmina  are  also  variable  though  always 
abbreviate,  and  in  most  of  the  species  are  longer  than  the  pronotum 
and  overlap,  but  in  the  first  tliey  are  shorter  and  distant.  The  hind 
tibiae  are  red  or  glaucous  and  have  nine  to  thirteen  spines  in  the  outer 
series. 

The  supraanal  plate  is  triangular  with  more  or  less  elevated  margins 
and  distinct  median  sulcus;  the  furcula  is  reduced  to  small  or  even 
minute  denticulations;  the  cerci  are  large,  constricted  in  the  mi(l<lle 
and  again  expanded,  more  or  less  incurved  and  sometimes  again 
apically  bent  in  the  original  direction;  the  subgenital  plate  is  broad, 
generally  produced  or  elevated  apically,  the  margin  entire. 

There  are  five  si)ecies,  all  occurring  west  of  the  Mississippi,  except 
one  which  is  found  in  the  upper  Mississippi  region;  of  the  others  two 
occur  in  Texas  (and  one  of  them  in  Kansas  also),  a  fourth  east  of  the

Sierra  Nevada  in  central  California,  ami  the  last  in  central  ^lexico.  I

to  one  of  the  Texan  species,  but  of  whi<'h  1  know  only  the  female,  and 
therefore  tlo  not  describe. 

This  series  represents  to  a  certain  extent,  in  brachypterous  forms, 
the  robustus  series  of  macropterous  species.

In  this  somewhat  homogeneous  group,  the  prozona  is  distinctly 
longitudinal  in  both  sexes  (the  female  of  one  species  is  not  known)  and 
nearly  or  quite  half  as  long  again  as  the  raetazona,  the  posterior  margin 
of  which  is  subtruncate  or  truncate  or  sometimes  very  obtusangulate. 
The  interspace  between  the  mesosternal  lobes  in  the  male  is  more  than 
twice,  sometimes  thrice,  as  long  as  broad.  The  tegmina  are  very  vari- 
able; one  species  is  <limorphic,  having  either  fully  developed  tegmina 
and  wings  considerably  surpassing  the  tips  of  the  hind  femora,  or 
ovate  lanceolate  overlapping  tegmina,  acuminate  at  tip  and  a  little 
longer  than  the  pronotum;  another  is  macropterous  with  subequal 
tegmina,  reaching  the  tii)S  of  the  hind  femora;  the  other  species  are 
l)rachypterous,  but  the  tegmina  are  variably  shaped, — sometimes  as 
in  the  brachypterous  form  of  the  dimorphic  species,  at  others  either 
rounded  ovate  and  attingent,  or  widely  sei)arated  and  lateral. 

The  supraanal  plate  is  triangular,  with  generally  a  tolerably  jdane 
surface;  the  furcula  is  obsolete,  subobsolete,  or  reduced  to  mere  brief 
(lenticulatious;  the  cerci  are  long,  constricted  in  the  middle,  but 
expanding  only  a  little  apically,  incurved,  and  bluntly  rounded  or 
inleriorly  subacuminate  at  tip;  the  subgenital  plate  is  always  small, 
distinctly  narrower  than  long,  often  narrowing  apically,  and  sometimes 
ends  in  a  tubercle. 

There  are  five  species,  most  of  them  widely  separated  from  one 
another:  one  occurs  in  the  upper  Mississippi  valley  from  the  Dakotas 
to  Kentncky,  while  the  others  are  found  respectively  in  Florida  (two 
si)ecies),  Texas,  and  California.

one  strongly  of  Paroxya.

This  is  a  tolerably  homogeneous  grouf),  in  which  the  prozona  of  the 
male  is  quadrate  or  nearly  so,  varying  from  a  little  longitudinal  (in  one 
s])ecies  distinctly  longitudinal)  to  a  little  transverse,  and  the  interspace 
between  the  mesosterual  lobes  in  the  same  sex  ranges  from  a  little 
longer  than  broad  to  twice  as  long  as  broad.  The  tegmina  are  always 
fully  developed,  rarely  do  not  surpass  the  hind  femora,  and  are  more

or  less,  generally  rather  vajrnely,  maculate  or  blotched.  The  hind 
tibiae  are  either  red  or  green,  usually  the  former,  and  have  ten  to  four- 
teen spines  in  the  outer  series. 

The  sui)raanal  ]>hite  is  pretty  regularly  triiio^'ilar,  the  ai)ex  never 
obtusangulate  and  generally  has  a  median  transverse  ridge  of  greater 
or  less  distinctness.  The  furcuhi  is  generally  a  mere  triangular  tooth 
shorter  than  the  last  dorsal  segment,  but  in  one  8i)ecies  is  wanting  and 
in  others  forms  a  pair  of  slender  spines  a  little  longer  than  the  last 
dorsal  segment.  The  eerei  are  of  modj^ate  wulth  and  invariably  forked 
more  or  less  distinctly,  sometimes  the  upi)er,  sometimes  the  lower  fork 
the  longer,  or  they  have  a  strongly  ungulate  median  process  beneath, 
which  stands  for  an  inferior  branch.  The  subgenital  plate  is  variable, 
but  is  generally  rather  broad  (but  sosnetimes  very  narrow)  anil  gener- 
ally a  little,  in  one  sjjecies  greatly,  elevated  apically. 

The  species,  nine  in  number,  are  of  small  or  medium  size,  occasion- 
ally a  little  above  the  medium.  Some  species  or  other  of  the  group  has 
been  reported  from  every  part  of  the  I'nited  States  excepting  Alaska 
and  California,  and  is  known  also  fnmi  the  immediately  neighljoring 
parts  of  the  Dominion  of  Canada  west  of  the  (ireat  Lakes,  but  none 
have  been  reported  from  Ontario  or  Quebec,  where  they  doubtless 
exist,  nor  from  the  Lower  Mississippi  Valley,  where  they  also  i)robably 
occur;  nor  is  a  single  species  known  from  any  jiart  of  Mexico.

One  of  the  smallest  if  not  the  very  smallest  macropterous  species  of 
^lelanoplus  known.  The  general  color  is  a  dark  griseons,  the  vertex 
of  the  head  marked  in  black  and  dull  yellow  in  a  somewhat  radiate 
fashion,  the  whole  face  and  sides  of  head  brownish  olive  or  sordini 
ycHow,  flecked  more  or  less  abundantly  with  black:  the  antennae  are 
l)ale  dirty  j-ellow,  becoming  infuscated  toward  the  tip;  behind  the  eye 
is  a  bro{.d  black  baud,  often  edged  with  yellow  above,  which  also 
traverses  the  ui»per  half  or  less  of  the  lateral  lobes,  confined  to  the 
prozona,  und  is  often  enlivened  by  a  small  pale  quadrate  patch  in  the 
center  of  the  lobes;  the  rest  of  the  latter  varies  from  yellow  to  brown, 
p.'dest  next  the  margins;  the  upper  surface  of  the  pronotum  varies  a 
good  deal,  but  is  usually  griseous,  often  with. a  median  belt  of  dirty 
yellow  or  ferruginous,  edged  on  the  front  of  the  nietazona  by  a  pair  of 
oblique,  crescentic,  longitudinal  or  converging  patches  of  black.  Teg-

with  a  pair  of  conspicuous,  very  oblitjue  pale  bars  at  the  middle  and 
next  the  base;  hind  tibiae  pale  glaucous,  occasionally  with  a  faint 
rufous  tinge,  becoming  paler  next  the  base  and  straw-yellow  at  the  tip, 
the  spines  more  or  less  heavily  black-tipped,  ten  to  eleven,  rarely 
twelve,  in  number  in  the  outer  series;  hind  tarsi  yellowish. 

Head  rather  large,  but  not  elevated,  and  moderately  arched ;  inter-

transverse  sulci  of  prozona  distinirt  throughout,  unusually  sinuous,  not 
severin*^  the  median  carina;  prozona  transverse,  occasionally  in  the 
male  subquadrate,  distinctly  lonj^er  than  the  metazona.  Prosternal 
spine  short,  stout,  erect,  conico-cylindrical,  appressed,  more  so  in  the

fnrcnla  consisting  of  a  i)air  of  adjacent,  subparallel  jirocesses,  each  of 
which  consists  of  a  tumid  base  bearing  an  apical,  equal,  slender,  arcuate

The  single  female  from  Newport  is  placed  here  with  some  doubt  on 
account  of  its  divergence  from  the  others;  and  all  the  specimens  have 
been  dried  after  long  immersion  m  alcohol,  bleaching  the  colors  to  some

of  male  (so  far  as  can  be  seen  on  the  sinf^U*  s[H»cimen  in  which  the  parts 
are  somewhat  concealed)  semiovate,  broadly  rounded  apieally,  lon;j:or

The  specimens  on  which  this  description  is  basetl  were  collected  in

broken  bhu'k  posto<'ular  band  crossin<i  the  prozona  on  the  upper  half 
of  the  lateral  lobes;  the  hind  femora  may  have  been  faintly  banded, 
the  hind  tibiae  were  probably  red,  with  black  spines,  and  there  is  a  dis- 
tinct row  of  fuscous  rectangular  spots  down  the  diacoidal  area  of  the 
tegmina,  especially  in  the  female.

1  have  never  again  seen  the  si)ecimens  on  which  this  species  was 
founded,  nor  any  others  that  could  be  referred  to  it.  Accordingly,  with 
slight  change  in  the  phraseology,  I  reproduce  the  original  devscription, 
to  which  I  may  add  the  following  unpubliohed  notes,  taken  while  the 
specimens  were  still  in  my  hands:  The  species  has  very  much  the  same 
general  appearance  as  .1/.  femurruhrum.  It  has,  however,  entirely  dif- 
ferent abdominal  appendages,  as  maybe  seen  above,  and  also  slenderer 
tegmina,  in  the  venation  of  which  it  closely  resembles  M.  lieeUri.  The 
prosternal  spine  is  not  very  large,  but  moderately  stout  and  bluntly 
rounded  at  tip,  a  little  appressed,  and,  on  side  view,  not  tapering;  the 
iiicsosternal  lobes  are  much  as  in  M.  leeleri.  The  median  carina  is  more 
distinct  on  the  metazona  than  on  the  prozona;  the  proi)ortions  of  the 
prozona  are  as  in  ^f.  l-ederi  and  the  whole  pronotum  almost  precisely 
as  in  that  species,  with  a  little  more  rounded  angle  to  the  hind  margin.

delicate  fuscous  maculation  along  the  discoidal  area;  wings  not  very 
broad,  hyaline,  sometimes  with  a  scarcely  perceptible  yellowish  tinge  to 
the  anal  area,  the  veins  fuscous  apically  and  anteriorly  so  as  almost  to 
give  the  tip  an  infumated  a])pearance.  Fore  and  middle  legs  tumes- 
cent in  the  male,  mottled  with  the  colors  of  the  face;  hind  femora 
alternately  marked  externally  with  faint  puri)lish  brown,  dark  brown 
and  very  pale  i)ur])lish,  the  inferioi'  carina  yellowish  bordered  with 
white,  the  under  surface  yellowish;  hind  tibiae  coral  red  with  a  basal 
black  annulation,  the  si)ines  tipped  with  black,  eleven  to  fourteen  in 
number  in  the  outer  series;  tarsi  of  all  the  legs  marked  with  fuscous 
deepening  into  black,  the  hind  tarsi  also  with  red.  Extremity  of  male 
abdomen  clavate,  a  little  recurved,  the  supraanal  i)late  triangular 
with  convex  sides  and  rectangulate  tip  the  lateral  margins  feebly 
elevated,  the  median  sulcus  as  in  the  preceding  species  but  with  rather 
less  prominent  walls;  furcula  present  only  as  slight  swellings  of  the 
inner  extremities  of  the  mesially  parted  lateral  halves  of  the  last  dorsal 
segment;  cerci  pale  brownish  compresse<l  laminae,  consisting  of  a  gently 
tapering  basal  half,  a  little  tumid,  straight  and  scarcely  twice  as  long 
as  the  basal  breadth,  and  a  bifurcate  apical  half,  the  forks  at  a  little 
less  than  a  right  angle  to  each  other,  equally  divergent  from  the  basal 
half,  the  lower  slight  and  subaculeate,  hardly  so  long  as  the  mesial 
breadth  of  the  stem,  the  upper  equal  or  subspatulate,  fully  half  as 
broad  and  nearly  as  long  as  the  stem,  incurved,  subsulcate  and  apically

It  has  also  been  reported  from  Staten  Island,  New  York  (Davis),  New 
Jersey  (Smith),  the  borders  of  Lake  Michigan,  in  Indiana  (Blatchley), 
and  Nebraska  (Bruner),  the  last,  I  think,  by  mistake. 

This  si)ecies  is  very  closely  allied  to  M.  hn-idus^  but  differs  in  its  lack 
of  any  projecting  part  to  the  furcula.  the  less  divergent  forks  of  the 
cerci,  less  elevated,  apical  margin  of  the  subgenital  i)Iate  and  greater 
niaculation  of  the  tegmina. 

I  first  observed  this  species  in  Sudbury,  Vermont,  in  August,  1808, 
abundant  in  the  vicinity  of  groves  in  dry  .ipland  pastures;  compara- 
tively few  M.  femur  ruhrum  occurred  with  them,  the  latter  being  found 
in  open  sunny  si)ots,  and  especially  in  hollows  in  the  lowlands. 
McNeill,  who  was  the  first  to  find  it  in  the  West,  says  that  in  Illinois 
^'it  is  restricted  to  the  tops  of  hills  and  the  sides  of  ravines  which  are 
too  barren  for  pasturage.'"  At  Provincetown,  Massachusetts,  I  found 
it  at  the  sandy  edges  of  neglected  cranberry  beds.  According  to 
Blatchley,  this  species  maybe  found  in  i>airing  time  ''among  the  leaves 
and  branches  of  the  iron-weed."  I  found  one  specimen  devouring  a  per- 
fectly dry  and  dea  1  hickory  leaf.  At  the  middle  of  August,  iq  Vermont, 
the  eggs  are  quite  undeveloj^ed,  the  ovaries  lying  as  mere  films  on  the

intestines  of  those  dissected.  The  first  pair  taken  in  eoitu  was  found 
August  10,  tlioujjli  in  Indiana  many  pairs  were  found  by  Blat<'hley  by 
tlie  tirst  of  Auj^ust.

In  this  group  the  male  prozona  is  (jnadrate  or  a  little  lonj»itudinal 
an('  the  interspace  between  the  mesosternal  lobes  of  the  same  sex 
twice  or  more  than  twice  as  long  as  broad.  The  eyes  are  rather  widely 
separated  and  the  frontal  costa  broad  and  e<|UJil.  The  i)ro8ternal  spine 
is  usually  long.  The  tegmina  are  fully  developed  or  only  a  little 
abbreviated  and  either  feebly  spot  ted,  longitudinally  streaked  or  wholly 
free  from  markings;  the  hind  tibiae  are  yellow  or  red,  with  from  ten  to 
twelve  spines  in  the  outer  series. 

The  supraaual  plate  is  shield  shaped  or  triangular  with  feebly  con- 
vex or  sinuous  sides,  and  with  the  surface  tolerably  Hat;  the  furcula  is 
entirely  wanting  or  in  one  or  two  instances  barely  indicated;  the  cerci 
are  excessively  br(»ad  and  stout,  ajjically  greatly  expanded  and  tlabel- 
late,  with  the  apic.il  border  either  convex  or  more  or  less  emarginate; 
the  subgenital  piate  is  longer  than  broad,  generally  moderately  nariow, 
a  little  elevated  apicallyand  sometimes  considerably  prolonged,  always 
entire. 

It  comprises  insects  of  the  largest  size  only  and  of  a  stout  and  bulky 
aspect.  Five  species  are  known,  occurring  in  the  southern  half  or 
more  of  the  United  States.

The  largest  of  our  speries  ol*  Melanoi)!!  and  lieavy  bodied;  excepting 
the  hind  legs  and  the  lateral  lobes  of  the  pionotnni,  the  general  color 
is  a  nearly  nniforin  l)r«»wiiish  testaceous,  becoming  paler  testaceous  in 
specimens  from  arid  regions;  in  those  from  Nebraska,  Kansas,  an<l 
Colorado  it  is  sometimes  a  blackish  green,  while  in  those  from  Illinois 
and  Indiana  it  is  often  of  a  dark  brownish  green.  The  head  has  some 
times  a  i)air  of  dnsky,  divergent  strii>es,  passing  from  the  posterior 
corners  of  the  fastigium  backward  across  the  vertex  and,  when  these 
are  present,  there  are  often  other  but  irregular  streaks  of  similar  tint 
on  the  genae  and  clouds  over  parts  of  the  face;  the  vertex  is  gently 
arched,  more  gently  in  the  female  than  in  the  male,  with  a  broad  inter 
val  between  the  eyes,  the  fastigium  broadly  and  not  very  deeply 
impressed;  frontal  costa  broad  but  narrower  than  the  interspace 
between  the  eyes,  percurrent,  eciual  except  for  a  slight  expansion  below, 
broadly  and  shallowly  sulcate  below  (and  including)  the  ocellus,  puuc 
tate;  eyes  moderately  prominent,  short,  not  a  great  deal  longer  than 
broad;  antennae  fulvo- testaceous,  nearly  twice  as  long  (male)  or  fully

inarjiin  obtusely  and  r«)undly  an«;ulate,  more  obtusely  in  sperimens 
from  the  Pacific  Coast  than  in  others,  the  median  carina  distinct  and 
sharp  on  the  metazona,  less  prominent  but  distinct  on  the  anterior  iialf 
of  the  prozona,  still  less  distinct  (occasionally  subobsolete)  between  the 
enlci;  prozona  snbquadrate  in  both  sexes,  smooth,  divided  in  the  mid- 
dle, and  barely  before  the  middle  of  the  posterior  half,  by  sulci,  the 
jaincipal  sulcus  bent  forward  in  the  middle  by  the  posterior  emarj>ina- 
tion  of  the  ])rozona,  the  metazona  plane,  finely  subrugnloso  punctate; 
lateral  lobes  nearly  vertical,  separated  from  the  disk  by  a  well  rounded 
angle  nowhere  forming  distinct  lateral  cariuac,  marked  next  the  upper 
limit  on  the  ])rozona  by  broken  blackish  i)atches,  frequently  reduced 
to  a  pair  of  short,  oblique,  black  dashes,  one  in  either  longitudinal  half 
of  the  prozona,  each  in  a  clearer  field,  and  also  by  the  blackening  of  the 
sulci  in  this  region;  they  are  sometimes  accompanied  by  slender, 
oblique,  parallel,  black  lines  lower  down,  the  hiiuler  the  lower;  the 
l>leural  incisures  are  also  heavily  marked  in  black*.  Prosternal  sjune 
rather  long,  conical  as  seen  from  the  side,  bluntly  cylin<lrical  as  seen 
from  in  front,  a  very  little  retrorse.  Tegmina  at  least  reaching  (female) 
or  distin<tly  surpassing  (male)  the  hind  femora,  absolutely  free  from 
niaculation,  the  narrowest  ai)ical  i)ortion  about  half  as  broad  as  the 
broadest  subbasal  jxution;  wings  pellucid  or  (in  darkest  forms)  very 
feebly  infumated,  feebly  and  narrowly  opaque  ah)ng  the  costal  margin, 
the  veins  and  cross  veins  mostly  brownish  luscous.  Fore  and  middle 
femora  of  male  heavily  bullate,  the  hind  femora  stout  and  rather  short, 
moderately  tumid,  generally  fulv(>  testaceous,  sometimes  flavo-testa- 
ceous  beneath,  the  outer  face  with  alternate,  fulvo  testaceous  and 
black,  narrow,  equal  fish-bone  markings,  the  black  rarely  interrupted 
ill  the  middle,'  the  upper  inner  face  witl»  small  basal  and  large  median 
and  postmedian  black  patches,  the  genicular  arc  black  on  both  inner 
and  outer  sides;  hind  tibiae  yellow  or  fulvous  (occasionally  in  California 
bright  coral  red),  with  a  postbasal  narrow  black  annulus  (in  dark 
specimens  more  or  less  infuscated  beyoiul  it),  the  sjjines  bhu-k  to  their 
very  base,  ten  to  eleven,  rarely  twelve,  in  number  in  the  outer  series. 
Extremity  of  male  abdomen  heavily  clavate,  the  supraanal  plate  sub- 
clypeate.  obtusely  angulate  at  apex,  the  margins  feebly  and  broadly 
elevated  and  the  median  jiortion  correspondingly  elevatnl  and  bearing 
on  its  summit  a  moderately  shallow,  longitudinal  suii-us,  tolerably 
broad  and  subequal  on  the  basal  half,  narrowing  an<l  with  falling  walls 
apically;  furcula  completely  absent  or  indicated  only  by  a  thickening 
«»f  the  last  dorsal  segment  at  their  proper  position;  cerci  very  large 

'  In  the  dark  forms  the  black  uiarkings  sometimes  run  together  and  cover  the

It  ajjpears  from  this  that  it  inhabits  the  Mississippi  Valley  from  as 
far  north  as  latitude  43'  to  the  (iulf,  and  the  re«;ion  to  the  west  as  far 
as  tlie  racitic,  from  a  somewhat  lower  latitude  to  central  Mexico.  I 
do  not  think  it  occurs  above  (»,(l()0  feet.  One  can  not  but  question  the 
accuracy  of  the  statement  that  it  occurs  in  New  .Jersey,'  as  it  has  never 
been  reported  el>ewhere  east  of  the  Allejihanies,  and  if  foun<l  there 
would  als«)  occur  farther  south;  so  laige  an  insect  and  so  distinct  from 
others  found  there  would  hardly  have  escaped  n«)tice  by  entomolo«;ists 
of  the  eastern  seaboard  in  Maryland  and  Virginia. 

The  oviposition  and  arranjiement  of  eggs  in  the  egg  ca]»sule  of  this 
insect,  as  well  as  its  parasites,  are  described  by  Biley  in  the  lirst  Beport 
of  the  Cnited  States  Kntomological  Commission,  and  with  its  life  his- 
tory are  later  summarized  by  him,  as  follows: — 

In  the  vittuity  of  St.  Louis,  Missouri,  tin-  lirst  specinicns  of  this  locust  w«>re 
olisorved  to  Uecoiiie  wiii<;«'(l  .Inly  19.  K<;«f»  wi-re  lai«l  Septmilici-  !».  As  a  'Icviation 
from  the  usual  e{;;i-layiii<;  habits  of  the  v;*'i»"s  .  .  .  th«*  e^gs  are  sonietiines  very 
numerously  jilaced  under  1»ark  of  lojj>  that  have  been  felled  ou  lov  lan<ls.  The  eg<;8 
of  this  sjiecies,  unlike  those  of  Hpntiin,  atl((nix  and  It miir-riihriiiii,  are  not  (juadri- 
linearly  but  irrei^ularly  arranjjed.  .  .  .  The  head  »iids  of  the  egjrs  in  the  pod  point 
mostly  outward.  <  >ne  hundred  and  seveury-live  eggs  have  been  couuteti  in  a  single 
mass.  • 

Mr.  Coquillett  has  made  some  interesting  observations  [in  California].  .  .  .  They 
atiiuirt'd  \vin<fs  from  the  last  week  in  .luue  to  the  last  wt-ek  in  .lulv  and  began  lav- 
ing  eggs  .Inly  US.  A  single  female  occnpit'd  7."»  minutes  in  (b'positing  an  egg-mass. 
The  situation  chosen  for  egg  laying  was  invariai)Iy  thf  edge  of  one  of  the  basin-like 
hollows  [for  irrigation?]  at  the  foot  of  a  tree.  This  locust  is  not  easily  startled, 
and  its  ordinary  tiight  is  rather  heavy,  and  sustained  only  for  a  distance  of  12  to  20 
feet. 

According  to  Thomas  and  Biley,  this  insect  is  occasionally  seen  fly- 
ing at  considerable  heights  and  apparently  migrating,  though  these  are 
rare  occurrences.  It  certainly  is  occasionally  one  of  the  most  destruc- 
tive pests  in  the  West,  particularly  in  Kansas,  Missouri  and  Illinois, 
and  it  has  been  noted  as  injuring  grass,  alfalfa,  Indian  corn,  beets, 
orchard  trees,  mulberry,  poplar  and  catali)a  trees,  and  even  grape 
vines;  also  dahlias,  hollyhocks  and  other  garden  flowers  have  been 
sj)ecitied  as  its  food,  not  to  mention  the  rag  weed,  Amhrosia  h-ifida. 


'Since  this  was  sent  to  the  printer  I  have  seen  specimens  from  Camden  County, 
New  Jersey,  in  the  collection  of  the  American  Entomological  Society.

This  group  is  nearly  related  to  the  robustus  series;  the  male  prozona 
is  more  or  less  distinctly  longitudinal,  and  tlie  interspace  between  the 
mesosternal  h>bt  -  of  the  same  sex  nearly  or  UKue  than  twice  as  long  as 
broad;  the  eyes  are  rather  widely  separated,  and  the  frontal  costa 
broad  and  e<iual.  The  prosternal  si)ine  is  i  ather  long  and  general'y 
slightly  retrorse.  The  tegmina  are  fully  developed,  at  least  as  long  as 
the  hind  femora,  without  spots  or,  rarely,  very  feebly  marmorate,  but 
sometimes  with  a  light  stri[>e  dividing  the  dorsal  and  lateral  faces  and 
extending  acrc;;s  the  pronotum.  The  hind  femora  are  longitudinally 
striped  on  the  outer  %ce  or  iv  marked,  the  hind  tibiae  usually  red, 
rarely  purplish,  with  ten  to  thii'teen  spines  in  the  outer  series. 

The  srpraanal  i)late  is  much  as  in  the  robustus  series:  the  furcula  is 
present  as  small  but  coarse  lobes,  and  the  eerci  are  much  as  in  the 
robustus  series,  but  less  extravagantly  developed;  the  subgenital  plate 
is  longer  than  broad,  generally  morierjitely  narrow,  somewhat  elevated 
and  sometimes  tliickened  ai)ically,  hardly  prolonged,  and  ^''  .»'ays  entire. 

It  comprises  insects  of  a  large  or  a  very  large  size,  with  heavy  bodies 
and  poor  in  flight.  Five  species  are  known,  and  among  them  they  cover 
our  entne  territo  v,  from  Atlantic  to  Prc'tic  and  from  Central  Mexico 
to  the  Saskatchewan  and  Hudson  Bay.  It  comprises  two  of  our  com- 
monest species.

It  has  also  been  reported  fron  Hudson  Bay  (Walker);  (^)uebec, 
Canada  {  Provancher),  and  Carolina  (Burmeister,  Saussure).  Its  range 
in  the  eastern  part  of  the  country  is  therefore  from  Hudson  Bay  to 
North  Carolina,  on  the  Pacific  Coast  from  A'ancouver  to  south<Mn 
California,  while  in  the  interior,  south  of  Canada,  it  occurs  in  less 
abundance  as  far  south  as  latitude  40"  or  thereabouts. 

An  examination  of  three  females  iii  Vermont  in  the  mi<ldle  of  August 
showed  thirty-nine  eggs  in  the  ovaries  on  one  side  and  thirty  on  the 
other  of  the  first;  forty-five  on  one  side  and  forty  two  on  the  otherof  the 
second;  and  thirtyeiglit  on  each  side  of  the  third,  the  total  nuniber  of 
eggs  varying  from  sixty-nine  to  eighty-seven.  A  fourth  female  had  no 
eggs  in  the  ovaries,  but  the  abdomen  was  filled  with  a  tilarian  worm 
id  bust  ttvo  feet  long;  loe  eggs  are  pale  yellow. 

This  insect  is  very  fond  of  i>erching  by  the  roadside  on  the  broad 
leaves  of  Inula  heUnlum,  sunning  itself.

ada(Scudder),(irand  Ifapids,  N\V.  T.(yuttin<,n.and  Nietoria  (Fletcher): 
also,  possibly,  from  M«'xico  (Saussnre).  It  therefore  ]>robably  raujij^es 
from  southern  rana<la  to  the  (lulf,  but  is  unknown  aonj^-  the  Atlantie 
Seaboard,  ami  wholly  unrei)orted  from  the  Pacific  Slope  south  of  NVash- 
injjton,  (unless,  as  above,  in  Me,\ico)  and  it  hardly  ranj^es  as  far  north 
as  M.  fenutrntus. 

IJruner  in  (uui  of  his  accounts  of  this  species  says  it  is  "a  lover  of 
rank  and  succulent  ve<;etatiou,  sut*h  as  is  found  upon  bottom  hnnls, 
alon^  the  edf:es  of  cultivated  fields,  at  the  margins  of  woodlands  and 
on  the  shadeil  mountain  sloi»es.''  When  "it  develoj)S  in  larj:e  num- 
bers, then  these  haunts  are  forsaken,  to  a  j-reater  or  less  extent,  and  it 
spreads  over  cultivated  fields,  eating  the  choicest  of  everythinj:."  In 
Iowa,  Mr.  J.  A.  Alh'u  found  it  conruon  on  dry  prairies,  as  well  as  in 
moist  sloujfhs  on  tall  <;rass. 

It  seldom  develops  any  marked  mijiratory  i)ropensity  and  its  e;L;.i;- 
laving  habits  "•differ  considerablv  from  those  of  the  smaller  miuratorv 
spe<*ies,  insomuch  as  })ut  one  or  two  clusters  or  pods  are  deposited  by 
a  "igle  female.  Nevertheless,  Just  as  many  e^jjs  are  laid  bv  each 
female  insect.  These  ejjjis  are  deposited  in  i)rairie  sod  or  any  comjjact 
vsoil  in  the  vicinity  of  the  regular  haunts  or  feedin<»"  places.  ( )hl  roads 
and  closely  cropped  i)astures.  when  located  handily,  are  favorite  resorts 
for  the  heavily  laden  females  when  attending-  to  this  mission  of  tiieirs.*' 
(Bruner.) 

Its  destructiveness  appears  to  be  mainly  confined  to  oiass.  jrrain, 
ami  garden  vegetables.  It  appears  in  the  winged  state  the  last  of 
June  or  early  in  July,  but  eggs  are  not  laid  until  late  in  August; 
sixty-two  to  seventy-two  eggs  have  been  counted  in  the  egg  i)ods  by 
Donald  Gunn  in  Manitoba. 

Blatchley  has  taken  the  male  of  this  species  in  eoitu  with  .1/.  femo- 
)((tu.Sj  aud  considers  them  the  same  species,  as  do  many  others.  The 
range  of  the  two  species,  which  are  certainly  very  closely  allied,  differs 
to  a  considerable  extent,  though  both  are  found  over  a  large  extent  of 
territory  side  by  side:  one  is  a  seaboard  a'ul  northern  form,  the  other 
an  interior  species.  Besides  the  dilierences  in  the  hind  tibiae,  which 
raiely  cause  hesitation  i'  attempting  to  separate  them,  there  are  slight 
difiereiices  which  1  have  attempted  to  state,  in  the  abdominal  append

Although  Thomas's  descri])tion  of  C.  yarroicii  was  based  upon  ;i 
female  only,  I  am  tolerably  confident  that  this  species  is  to  be  referred 
to  it;  it  certainly  fits  it  better  than  any  known  to  me,  and  its  reference 
here  was  suggested  to  me  by  Professor  Bruner.  Thomas  gave  no  locality 
beyond  "found  in  the  collection,''  which  was  made  in  '4)ortions  of 
Nevada,  Utah,  California,  Colorado,  New  Mexico  and  Arizona."  He 
afterwards  mentions  it  as  "probably  from  Arizona,  biit  possibly  from 
Nevada,''  without  giving  reasons.  From  all  that  appears  it  might  have 
come  as  well  from  Colorado  or  Utah.

low  broad  walls,  a  little  constricted  in  the  apical  half;  furcula  consist- 
ing of  a  pair  of  slight  acumiuate  denticulations,  arising  from  the  thick- 
ened inner  extremities  of  the  divided  halves  of  the  last  dorsal  seg- 
ment, and  overlying  the  ridges  bounding  the  median  sulcus  of  the 
supraanal  plate;  cerci  large  and  broad,  gently  incurved,  slightly  taper- 
ing on  the  basal  half,  and  then  expanding  into  a  transversely  suboval 
apical  flabellation,  nearly  half  as  broad  again  as  the  extreme  base, 
expanding  more  above  than  below,  the  apical  margin  broadly  convex, 
the  whole  considerably  surpassing  the  supraanal  plate;  infracercal 
plates  surpassing  but  slightly  the  sides  of  the  supraanal  plate,  about  as 
long  as  it;  subgenital  plate  moderately  broad,  the  lateral  margins 
hardly  elevated  apieally,  but  considerably  prolonged,  subtuberculate. 

Length  of  body,  male,  23  mm.,  female,  29  mm.;  tegmina,  male,  20 
mm.,  female,  24.5  mm.;  hind  femora,  male,  13.75  mm.,  female  15.75  mm. 

Three  males,  2  females.  Los  Angeles,  California,  Coquillett,  July 
(L.  Bruner;  U.S.N.M. — IJiley  collection). 

This  is  the  smallest  and  at  the  same  time  the  slightest  species  in  this 
series. 

28.  PrNCTrLATTJS  SERIES. 

This  group  is  composed  of  species  with  prominent  head  and  rapidly 
declivent  fastigium,  and,  in  the  male,  very  prominent  eyes.  The  joints 
of  the  antennae  are  unusually  long.    The  pronotum  is  rather  short  and

in  front  rather  flaring  to  receive  the  head,  the  prozona  quadrate  (male) 
or  distin<'tly  transverse  (female),  the  prostenial  spine  short,  conical, 
and  erect,  and  the  interval  between  the  mesosternal  lobes  relatively 
broad.  The  tegmina  are  fully  developed,  longer  than  the  hind  femora, 
maculate  over  their  whole  breadth.  The  hind  femora  are  twice  rather 
narrowly  belted  with  black,  and  the  hind  tibiae  red,  more  or  less 
obscured. 

The  supraanal  i)late  of  the  male  is  triangular,  the  furcula  very  slight 
or  wanting,  the  cerci  very  large  and  broad,  immensely  expanded  api 
cally  and  Habellate,  with  convex  apical  margin,  the  subgenital  plate 
very  much  prolonged  and  greatly  elevated  apically. 

The  insects  are  of  medium  or  large  size  and  dark  color,  much  mot 
tied,  and  live  as  far  as  known  only  on  coniferous  trees.    Two  species 
are  known,  one  from  the  Southwest,  the  other  over  a  large  part  of  the 
country  east  of  the  IJocky  Mountains. 

130.  MELANOPLUS  ARBOREUS,  new  species. 

(Plate  XXV,  tig.  5.)  ^  * 

Dull  grimy  olivaceous,  heavily  spotted  and  clouded  with  brownisli 
and  blackish  fuscous,  giving  it  a  more  or  less  conspicuously  mottled 
ap])earance.  Head  very  large  and  exceptionally  i)rominent :  in  brightest 
specimens  livid  or  dull  pale  tlavous,  heavily  and  irregularly  flecked  with 
very  dark  olivaceous  inclining  to  blackish  fuscous,  forming  more  or  less 
well  marked  stripes,  bordering  the  upper  part  of  the  eyes  and  following 
the  median  line  of  the  vertex;  vertex  tumid;  interspace  between  the 
eyes  rather  narrow,  narrower  than  the  frontal  costa;  fastigium  rapidly 
declivent,  sulcate,  the  sulcation  broadening  a  little  anteriorly ;  frontal 
costa  moderately  broad,  eipial,  laterally  punctate,  at  and  below  the 
ocellus  sulcate;  eyes  large,  very  prominent,  particularly  in  the  male; 
antennae  pale  flavous,  becoming  ferruginous  apically,  infuscated  broadly 
and  obscurely  at  intervals  throughout,  a  little  longer  (male)  or  a  little 
shorter  (female)  than  the  hind  femora.  Pronotum  very  feebly  subsel- 
late,  the  metazona  flaring  slightly  and  the  prozona  distinctly,  though 
over  but  little  space,  to  receive  the  head,  the  front  margin  faintly  con 
vex,  the  hind  margin  broadly  augulate,  the  angle  broadly  rounded,  the 
whole  brownish  fuscous  or  yellowish  brown,  more  or  less  mottled 
(except  on  the  metazona)  with  olivaceous  or  dull  flavous  and  with  fus 
cous,  the  latter  (sometimes  tinged  with  olivaceous)  forming  on  the 
upper  half  of  the  lateral  lobes  a  broad  more  or  less  broken  band;  pro 
zona  gently  convex  tranversely,  passing  insensibly  into  the  inferiorly 
vertical  lateral  lobes,  quadrate  (male)  or  distinctly  transverse  (female), 
a  half  (male)  or  a  fourth  (female)  as  long  again  as  the  metazona, smooth, 
the  median  carina  very  feeble,  subobsolete  between  the  sulci,  but  dis 
tinct  though  slight  on  the  metazona ;  the  latter  punctate,  with  feebly 
indicated  lateral  carinae.  Prosternal  spine  short,  conical,  bluntly 
pointed,  erect ;  interval  between  mesosternal  lobes  slightly  longer  than

broad  (male)  or  slightly  broader  than  Ion*?  (feinalo).  Tefrmina  anri)as8- 
iiig  considerably  the  hind  femora,  gently  and  feebly  tapering  fioin  tlie 
siibbasal  expansion  to  the  well-rounded  tij),  fusco-testaeeous  with  an 
olivaceous  tinge,  distantly  and  uniformly  Hecked  with  usually  roundish 
or  subquadrate  dark  fuscous  spots,  less  abundant  in  the  apit-al  third, 
but  not  contined  at  all  to  the  discoidal  area:  win<;s  smok}' i)ellucid, 
beeoming  feebly  infuseated  apicall}",  the  veins  and  cross-veirs  mostly 
blackish  fuscous.  Fore  and  middle  femora  luteo-ferruginon,-,  tiecked 
with  dark  olivaceous  or  fuscous;  hind  femora  varying  from  sordid 
luteo-fuscous  to  dull  i)ale  olivaceous,  rather  narrowly  and  completely 
bifasciate  with  bljick,  forming  unusually  regular  transverse  ban<ls,  the 
whole  apex  blackish  fuscous  or  black;  hind  tibiae  plumbeo-fuscous  at 
extreme  base,  followed  by  a  very  narrow  black  annulus  and  this  by  a 
broader  pale  annulus,  beyond  which  the  tibiae  are  dull  red,  obscured 
above,  excepting  at  apex,  and  sometimes  on  the  sides  for  a  similar  and 
beneath  for  a  brief  distance,  with  fuscous,  often  broken  into  Hecks, 
the  whole  pilose  above;  spines  black  nearly  or  quite  to  their  base, 
ten  to  twelve  in  number  in  the  oxt  er  series.  Extremity  of  male  abdo- 
men feebly  clavate,  m.uch  upturned,  the  sui)raanal  plate  broad,  triangu- 
lar, with  nearly  straight  lateral  margins,  acutangulate  tip  (too  nearly 
rectangulate  in  our  figure),  with  a  broad  and  rather  shallow  median 
sulcus,  interrupted  beyond  the  middle,  and  in  the  basal  half  bounded 
by  raoderatelj'  high  walls;  furcula  composed  of  a  pair  of  slight  trian- 
gular projections  at  the  inner  angles  of  the  divided  last  dorsal  segment, 
overlying  the  ridges  of  the  supraanal  plate ;  cerci  large,  subequal  on  the 
basal  two-fifths  or  more,  then  abruptly  expanding  into  a  transverse 
apical  flap,  twice  as  broad  as  the  base,  the  expansion  almost  wholly  on 
the  upper  side  and  at  right  angles  to  the  basal  portion,  the  apical 
margin  broadly  convex,  but  below  emarginate  to  form  a  denticulation 
of  the  lower  posterior  angle  of  the  flap,  the  whole  gently  incurved 
and  surpassing  the  supraanal  plate ;  infracercal  plates  wholly  concealed 
beneath  the  supraanal  plate;  subgenital  plate  moderately  broad,  very 
greatly  extended  and  abruptly  elevated  at  the  extreme  apex. 

Length  of  body,  male,  30  mm.,  female,  44  rnm.;  antennae,  male,  IS 
mm.,  female,  16.5  mm.;  legmina,  male,  26  mm.,  female,  31  mm.;  hind 
femora,  male,  16  mm.,  female,  21  mm. 

Six  males,  2  females.  Dallas,  Texas,  Boll  (U.S.N.M. — Riley  collec- 
tion ;  S.  H.  Scudder) ;  Gulf  coast  of  Texas,  Aaron ;  Arizona,  Schaupp 
(L.  Bruner). 

This  species  is  certainly  very  closely  allied  to  M.  2)unctuIaiuSy  which 
not  only  occurs  with  it,  but  over  a  much  wider  extent  of  country:  itis 
a  much  larger  insect  and  differs  in  several  points  in  the  abdominal 
appendages  of  the  male,  thougli  it  is  possible  that  the  t  vo  i!>Lould  be 
looked  upon  as  races  of  a  single  sx)ecies.

(McNeill),  and  eastern  Nebraska  (Bruner). 

Bruner  reports  it  from  oak  groves  and  Smith  on  cranberry  bogs,  but 
Beutenmiiller  has  found  that  it  lives  on  pine  trees.  Blatchlej'  found  it 
in  the  depths  of  a  tamarack  swamp,  and  says  it  is  not  an  active  insect, 
"usually,  after  one  or  two  short  leaps,  sciuatting  close  to  the  earth,  and 
seemingly  depending  upon  the  close  similarity  of  its  hues  to  the  gray- 
ish lichens  about  it  to  avoid  detection."  Others  have  since  found  it  on 
coniferous  trees,  and  these  are,  apparently,  its  proper  station.

nate,  attingent,  slightly  longer  than  the  i>ronotum,  or  fully  develo)>ed, 
surpassing  the  hind  femora,  rather  broad  and  ecjual,  well  rounde<l  at 
tip,  hardly  tapering  in  the  distal  half,  at  a  distance  from  the  ai)ex 
eiiual  to  the  breadth  of  the  tegmina  as  broad  as  the  metazona,  the 
intercalaries  and  cross  veins  of  the  discoidal  area  everywhere  few,  the 
venation  in  general  loose,  irregular,  and  ill-detine<l,  the  humeral  vein 
broadly  sinuous,  terminating  on  the  costal  margin  at  least  as  far  before 
the  apex  as  the  breadth  of  the  tegmina,  nowhere  running  closely  par- 
allel to  the  costal  margin  nor  gradually  merging  into  it,  the  area  inter- 
calata  not  reaching  the  middle  of  the  tegmina.  Hind  femoia  long  and 
Blender,  the  genicular  lobes  pallid  with  a  transverse  basal  fuscous 
stripe,  the  hind  tibiae  glaucous,  sometimes  yellowish,  with  eleveii  to 
thirteen  spines  in  the  outer  series.  Abdomen  compressed,  medially 
carinate,  apically  clavate  and  recurved  in  the  male,  the  subgenital 
plate  narrow  and  long,  with  lateral  margins  ampliate  at  base,  the 
ai»ical  margin  niesially  i)inched  but  not  elevated,  the  apical  face  with 
no  subapical  tubercle;  furcula  delicately  dev^eloped ;  cerci  compressed 
styliform,  rather  small;  ovipositor  of  female  normally  exserted. 

This  genus  is  very  closely  related  to  Mdanoplus^  from  which  it  is  to 
be  distinguished  by  its  large  tumid  head  and  subsellate  equal  prono- 
tum,  as  well  as  bj'  its  substyliform  cerci,  though  the  last  characteristic 
is  found  in  some  degree  in  a  couple  of  species  of  Melanoplus.  The 
neuration  of  the  tegmina,  when  the  latter  are  developed,  also  differs  to 
a  certain  degree,  pointed  out  in  the*  descriptions.  Bruner'  has  already 
expressed  the  opinion  that  this  tyjie  should  be  geuerically  dissociated 
from  other  Melanopli. 

A  single  species  is  known,  found  in  the  western  Mississippi  basin 
and  bevond  its  latitudinal  limits  from  Alberta  to  Mexico.

Body  straight,  subcylindrical,  briefly  pilose.  Head  moderately  large, 
not  prominent,  the  face  subdeclivent,  the  eyes  large,  prominent,  hah  as

or  very  much  more  than  (female)  the  width  of  the  basal  joint  of  the

obtusely  and  blniitly  aiifnilate;  lateral  lobes  vertical,  their  lower  border 
very  obtusely  aii;;ulati'  in  tiie  middle.  Prosternal  spine  i>r(>minent, 
subeylindrical,  bluntly  pointed,  laterally  eonipressj'd  al  the  base,  at

lobes  (female).  Te^niiiia  jind  win«;s  variable,  but  at  least  as  \o\\^  as 
the  pronotuni.  Hind  femora  reaching  or  fjenerally  surpassing;  the  tip  of 
the  abdomen,  UKMlerately  stout  but  taperinj;  very  regularly,  unarnuMl 
above,  the  inferior  genicular  lobes  pnxluced  but  apically  rounded, 
nnirked  at  base  with  a  transverse  dark  bar;  spined  margins  of  hind 
tibiae  smooth,  scarcely  dilated  toward  the  tip,  juovided  on  outer  margin 
with  nine  to  thirteen,  generally  eleven,  spines,  the  larger  nund)er  being 
more  common  in  the  female.  Subgenital  plate  of  male  short,  transverse, 
of  subequal  width  throughout,  more  or  less  tumid,  the  lateral  margins 
nmpliato  at  the  base;  aiml  cerci  of  male  long,  lannnate,  subclepsydral 
in  shape,  incurved;  edges  of  inferior  valve  of  ovipositor  smooth. 

This  genus  bears  a  <;lo8e  general  resemblance  to  the  geront(»geic 
genus  Oxya,  but  difl'ers  strikingly  frcmi  it  in  the  separated  metasternal 
lobes  of  the  female,  the  blunt  tips  of  the  inferior  genicular  lobes  of  the 
hind  femora,  the  smooth  edges  of  the  hin<l  tibiae  and  the  absence  of 
the  terminal  spine  of  the  outer  series  of  the  same.  It  is  very  narrowly 
separable  from  Melanoplus,  and  I  do  not  see  how  it  could  be  distin 
guished  from  it  if  we  include  in  it,  as  Still  did,  his  Pvzotettir  plebejus 
ijud  nisticus.  The  combination  of  such  peculiarities  as  the  long 
antennae  and  strongly  transverse  subgenital  plate  of  the  male  with 
the  long  and  parallel  sided  i)ronotum  of  both  sexes  serves  to  distin- 
guish it  from  Melanoplus,  as  here  limited;  while  the  strongly  banded 
sides  of  the  body  and  the  long  and  clepsydral  cerci  of  the  male  in  all 
the  species  mark  it  as  a  peculiar  type  even  if  the.^e  markings  and  form 
of  genitalia  do  occur  in  certain  species  of  the  diversified  genus 
Melanoplus. 

Three  species  are  known  and  appear  to  be  confined  almost  entirely  to 
our  Atlantic  and  Gulf  borders,  though  some  of  the  species  occur  as  far 
inland  as  Indiana,  Ohio,  and  Michigan.  It  is  unknown  west  of  the 
^Mississippi,  except  in  Louisiana  and  Texas  (though  Professor  Bruner 
suspects  its  presence  in  Nebraska).    They  inhabit  moist  places.

fuscous,  more  or  less  tinged  with  castaueous:  behind  tlie  eyes  a  broad, 
straight,  horizontal,  black  band,  edged  more  or  less  distinctly,  both 
above  and  below,  with  yellowish:  antennae  varying  in  length,  being 
relatively  longer  in  southern  than  in  northern  exaniides,  but  genenilly 
about  two-thirds  as  long  as  the  body  in  the  male,  yellow  at  base, 
beyond  testaceous,  deepening  into  fuscous  toward  the  tip,  the  ai>ices 
of  the  joints  normally  i)allid.  Upper  surface  of  the  pronotuni  of  the 
color  of  the  top  of  the  head,  the  upi)er  half  of  the  deflected  lobes  with 
avery  l)road  black  band  in  continuation  of  that  on  the  head,  anteriorly 
edged  more  or  less  distinctly,  both  above  and  beh»w,  with  yellowish 
and  generally  fading  out  before,  or  abruptly  terminating  at,  the  meta- 
zona  (in  the  earlier  stages  it  continues  uninterruptedly  across  the  pro- 
notum,  and  this  persistence  is  occasionally  shown  in  the  adult,  or  is 
indicated  on  the  metazona  by  a  brown  band  sometimes  percurrent  and 
usually  reduced  in  width);  pleura  with  a  horizontal  stigmatal  stripe 
running  backward  from  the  hinder  edge  of  the  mesothoracic  episterna 
(sometimes  confined  to  the  mesothoracic  epimera),  and  an  oblique  stripe 
nearly  following  the  division  line  between  the  metathoracic  episterna 
and  ejumera;  when  the  lower  stripe  is  complete  it  renders  the  meta- 
thoracic episterna  conspicuous,  especially  in  the  male,  on  account  of 
the  cuueitbrm  oblique  yellow  dash  which  lies  between  these  two  black 
stripes.  HiTid  margin  of  pronotum  less  distinctly  aiigulate — that  is, 
more  uniformly  rounded — than  in  the  other  species,  though  the  differ- 
ence is  but  slight  and  sometimes  disappears.  Tegmina  nearly  uniform 
brownish  fuscous,  often  with  a  faint  line  of  small  Heckings  down  the 
middle  in  the  female.  Legs  of  the  color  of  the  body,  the  middle  and 
hind  femora  generally  more  or  les^  infuscated  on  their  outer  face,  the 
upjier  half  of  the  genicular  lobes  of  the  latter  black ;  hind  tibiae  glaucous 
with  black  or  blackish  spines.  Supraanal  plate  of  male  long  triangular 
with  a  broad  mesial  rounded  ridge  extending  two-thirds  its  length,  on 
the  summit  of  which,  in  the  basal  half  of  the  plate,  is  a  very  narrow 
deei)  sulcus  which,  after  interruption,  is  repeated  again  in  the  apical 
toartli;  furcula  consisting  of  a  pair  of  moderately  long,  moderately 
slender,  cylindrical,  slightly  tapering,  blunt,  adjacent  fingers  (shorter 
than  usual  in  the  specimen  figured  and  drawn  too  stout),  often  diver 
gent;  cerci  lamellate,  very  long,  strongly  incurved,  gradually  narrow- 
ing and  then  as  gradually  enlarging,  so  as  to  make  the  spatulate  ti]) 
nearly  as  broad  as  the  base,  the  ax)ical  margin  rounded  and  subemar- 
ginate. 

The  tegmina  are  ordinarily  of  about  the  length  of  the  body,  but,  in 
the  South  i)articularly,  it  often  occurs  with  tegmina  only  reaching  a 
little  beyond  the  middle  of  the  abdomen.  I  have  seen  one  such  from 
Massachusetts;  and  in  a  pair  from  Fort  Worth,  Texas,  in  the  National 
Museum  the  tegmina  are  scarcely  longer  than  the  ]>ronotum  and  sub- 
acuminate  at  tip.    This  form  may  receive  the  racial  name  iexana."

20.   POECILOTETTIX,   now  genus. 
{UoixiXo?,  mottled;  rerr/?,  gra8shopi)er.) 

Head  and  body  with  the  general  aspect  of  ]\Ielanoplus.  Head  nearly 
vertical,  especially  in  the  female,  the  eyes  moderately  large,  moderately 
prominent  in  the  male,  broad  oval,  not  more  than  half  as  long  again  as

notum  together.  Pronotum  enlarging  very  slightlj'  posteriorly,  the 
suture  between  prozona  and  metazona  deeply  impressed,  with  rounded 
walls;  the  prozona  scarcely  or  but  little  longer  than  the  metazona, 
coarsely  and  distantly  punctate,  the  transverse  sutures  distinct  and 
rather  heavy,  transversely  broadly  convex  with  no  lateral  carinae;  the

metazona  Hnely  and  closely  punctate,  8lij,'litly  tumid  in  the  female, 
the  angle  of  the  lateral  (^arinae  well  rounded,  the  posterior  border 
broadly  angulato  convex,  marj^ined;  median  carina  obsolete  or  sub- 
obsolete  throughout.  Prostemal  spine  slender,  straight,  acuminate; 
nieso-  and  metastethia  together  longer  than  broad;  interval  between 
mesothoracic  lobes  distinctly,  generally  very  much,  longer  than  broad, 
generally  broader  in  the  female  than  in  the  male,  the  metasterral  lobes 
subattingent  or  approximate,  the  portion  of  the  metaster?jum  behind 
the  lobes  small,  hardly  more  than  twice  as  broad  as  long.  Tegmiiia 
fully  developed  in  all  known  species',  remarkably  uniform  in  width, 
with  the  costa  very  slightly  exi)anded  near  the  base,  and  a  strongly 
and  uniformly  rounded  apex.  Hind  femora  moderately  slender,  with 
immaculate  inferior  genicular  lobes,  the  tibiae  with  eight  to  nin«*  exter- 
iial  spine*!.  Cerci  of  male  extremely  slender  beyond  the  tapering  lami- 
nate base,  tuefurcula  subobsolete;  the  lateral  margins  of  the  subgenital 
plpte  ampliate  at  base  and  the  apex  provided  with  a  distinct  tubercle; 
the  pallium  often  has  a  pyramidal  erection. 

P.  picticorniis  (Thomas)  may  be  regarded  as  the  type. 

As  far  as  known,  this  genus  occurs  only  on  the  Pacific  coast,  near 
our  southern  borders.  It  is  remarkable  for  the  tuberculate  abdomen, 
resembling  He^perotettii\,  but  apical  instead  of  subapical,  and  for  the 
sometimes  vivid  and  always  exceptionally  variegated  colorings  of  its 
different  species.

fessor L.  Bruner  writes  me  that  he  has  received  the  same  species  from 
Tepic,  Jalisco,  Mexico. 

This  insect  may  be  instantly  distinguished  from  every  other  in  the 
entire  group  of  Melanopli  by  its  peculiar  blackish  punctuation  and  the 
annulate  antennae.  I  had  an  opportunity  of  studying  the  tyi)e  manj'^

(OMaAf'o?,  swollen  ;   Kfr>ro?,  bsuk.) 

Body  stout, heavy  and  'Uimsy.  Head  large  and  full,  the  vertex  well 
arched,  raised  considerably  above  the  level  of  the  prothorax,  the  fas- 
tigium  broad,  broadly  and  sijaHowly  sulcate  and  considerably  declivent, 
♦hf  ey*»a  separated  rather  widely;  face  nearly  vertical:  frontal  costa 
very  bioad,  subeijual,  nearly  plane,  percurrent  but  sometimes  obscure 
basally;  eyes  rather  large,  not  very  prominent,  broa<lly  ovate,  with  a 
slight  production  above  anteriorly;  antennae  not  slender,  uniform, 
slightly  longer  (male)  or  slightly  shorter  (female)  than  head  and  pronotum 
together.  Pronotum  short  and  stout,  enlarging  posteriorly  only  by  the 
slight  Hare  of  the  metazon;'.,  with  vertical  though  slightly  tumid  lateral 
lobes,  more  or  less  tlaring  on  the  metazona  below,  separated  from  the 
dorsum  by  more  or  less  pronounced,  coarse,  rounded  rugae,  generally 
interrupted  on  the  posterior  portion  of  the  prozona,  the  median  carina 
interrupted  between  the  sulci;  disk  of  prozona  distinctly  tumid,  but 
little  longer  than  the  metazona,  from  which  it  is  separated  by  a  very 
deep  sulcus,  its  own  posterior  transverse  sulci  deeply  impressed, 
approximate,  and  subparallel,  the  anterior  submargiual  sulcus  also  very 
distinct,  the  margin  being  elevated  to  receive  the  head ;  metazona  plane, 
puuctato  rugulose,  very  obtusely  angulate  behind,  the  border  margi- 
uate.  Prosternal  spine  short,  conical,  blunt;  meso-  and  metastethia 
together  distinctly  longer  than  broad  in  both  sexes,  the  mesosternal 
lobes  a  little  longer  than  broad  in  both  sexes,  the  metasternal  lobes 
subattiugent  in  the  male,  slightly  distant  in  the  female,  the  space 
behind  the  latter  laterally  elongate,  extending  forward  to  the  coxae. 
Tegmina  fully  developed  or  abbreviate,  rarely  shorter  than  the  prono- 
tum and  theu  but  slightly.  Hind  femora  stout,  heavy,  and  tumid,  the 
inferior  genicular  lobe  pallid,  immaculate.  Abdomen  of  female  with 
abbreviated  terminal  segments  (recalling  Bradynotes)  and  partially 
exserted  ovipositor;  of  male  not  enlarged  at  the  extremity  and  scarcely 
deviated,  terminating  roundly  and  bluntly,  the  last  ventral  segment  (in 
advance  of  the  subgenital  plate)  scarcely  longer  than  the  penultimate; 
subgenital  plate  of  male  very  brief  and  subequal,  its  lateral  margins 
distinctly  ampliate  at  the  base  and  entire  apically,  with  no  tubercle; 
cerci  tumid  and  enlarged  at  base,  suddenly  contracted,  and  terminating 
in  a  slender  posterior  process. 

This  genus  is  quickly  separated  from  those  in  its  immediate  vicinity 
by  the  tumidity  of  the  prozona,  and  the  clumsy  form,  which  give  it  a 
very  distinct  appearance.

Bruner  reports  the  species  also  from  Nevada  and  Arizona. 

Palmer  fcmnd  this  species  on  grassy  slojies,  beside  brooks. 

The  form  cniiima  appears  to  be  the  only  one  found  in  the  northern 
part  of  the  range  of  the  species  north  of  central  Calitornia,  and  the 
form  (oUa^fs  is  rtirely  met  with  anywhere. 

The  iV  rent  forms  have  not  been  taken  //*  coitn  with  eacli  other,  so 
far  as  I  know.  The  form  juvundus  besides  having  very  short  tegmina, 
is  noticeably  smaller  than  the  otliers. 

I  can  scarcely  think  the  tbrm  collaris  to  be  the  insect  described  by 
Thomas  as  Caleopteuiift  [sic]  ffavolincatua,^  as  Bruner  has  supposed. 
Thomas's  description  very  poorly  tits  it;  he  makes  no  mention  of  the 
tumid  prozona,  and  he  states,  both  here  and  subsecpiently,-  that  it 
closely  resembles  Mehinoplus  sprrtusy  and  that  the  ]>osterior  margin  of 
the  subgenital  plate  of  the  male  is  notched,  whereas  its  general  appear- 
ance is  very  different  indeed  from  M.  sprctus;  so  much  so  that  it  can 
hardly  be  believed  that  anyone  would  select  it  for  comi>arison ;  nor  has 
the  apical  margin  of  the  subgenital  i)late  the  faintest  sign  of  any 
emargination.  Thomas's  specimen  was  derived  from  Crotch's  collection 
in  the  Museum  of  Comparative  Zoology;  Crotch  collected  OedaleouotKft 
enigma  coUaris  in  central,  not  southern,  California,  whereas  Tho.ias 
gave  his  C.  JiavolineatuK  from  southern  California.  Thomas's  description 
does  not  at  all  tit  any  species  from  southern  California  which  has  come 
under  my  notice,  and  until  such  a  form  occurs  his  name  should  go  for

Bruner  states  that  the  Montana  specimens  were  taken  near  FTelena

disk  in  both  sexes  transversely  convex  and  passing  quite  insensibly 
into  the  vertical  lateral  lobes;  the  ground  color  of  the  pronotum 
is  Havo-testaceous,  but  it  is  heavily  overlaid  with  black  somewhat 
irregularly,  which  however  forms  a  broad  dorsal  band  (divided 
in  the  female  by  a  mediodorsal  tlavous  stripe)  crossing  the  jirozona 
only,  and  very  broad  vk-eous  (male)  or  brownish  fuscous  (female)

male,  ferrugineo  fiavous;  hind  femora  varying  from  fiavo-testaceous  to 
ferruginous  and  very  broadly  bifasciate  with  black,  the  fasciations  so 
confused  on  the  outer  face,  especially  in  the  female,  that  this  often 
becomes  wholly  black  with  more  or  less  pronounced  fiavous  incisures, 
the  lower  nuirgin  of  the  outer  face  fiav^ous,  sometimes  linearly  dotted 
with  black,  the  lower  face  more  or  less  sanguineous,  the  sides  of  the

considerably  recurved,  the  snpraanal  plate  triangfular  with  blunt  apex, 
the  sides  nearly  straight,  feebly  eraarginatejust  before  the  middle,  but 
scarcely  at  all  elevated,  the  median  carina  very  deep  in  the  basal  half 
between  high  and  sharp  walls,  beyond  shallow  and  feeble  but  percur- 
rent;  furcula  consisting  of  a  pair  of  approximate,  minute,  sleader,  par- 
allel, blunt  lingers,  no  longer  than  the  last  dorsal  segment;  cerci  very 
long  and  slender,  exteriorly  a  little  tumid,  bent  arcuate,  tapering 
gradually  to  the  middle  to  less  than  half  the  basal  breadth,  then  bent 
roundly  inward  and  thereafter  equal,  blunt-tipped,  their  tips  meeting 
over  the  apex  of  the  sujmianal  plate;  subgenital  plate  short,  slightly 
broader  apically  than  at  base,  almost  twice  as  long  as  broad,  the  lateral 
margins  strongly  roundeil  at  base,  with  the  apical  margin,  as  seen  from 
above,  very  strongly  rounded,  not  elevated,  entire.

By  the  kindness  of  Doitor  Aurivillius  of  Stockholm,  I  am  able  to 
illustrate  the  male  abdomen  of  Stal's  type  (tig.  9),  which  I  should  have 
been  unable  to  identify  with  certainty  from  the  rather  meager  descrip- 
tion. I  do  not  find  the  apex  of  the  hind  tibiae  black,  as  St^l  states 
them  to  be.

Body  compressed,  especially  in  the  female,  where  it  is  also  feebly 
fusiform,  feebly  pilose.  Head  projecting,  front  strongly  oblique,  whole 
summit  of  head  horizontal,  scarcely  convex,  triangular;  eyes  nearly 
meeting  above,  especially  in  the  male,  where  they  are  separated  by  a 
space  not  wider  than  the  narrowest  part  of  the  frontal  costa,  the  fastig- 
jum  in  front  of  them  laterally  expanded  and  slightly  tumid;  front  sub- 
appressed,  particularly  in  the  female,  almost  straight;  eyes  long  oval, 
moderately  prominent,  in  the  female  depressed  and  tapering  above; 
antennae  moderately  slender,  linear,  subdepressed,  about  as  long  as

roundly  excised.  Prosternal  s]»iiie  blunt,  conicoeylindrical ;  inner  mar-

(male)  or  distant  from  each  other  by  half  their  width  (female);  meta- 
sternal  lobes  subcontiguous  in  both  sexes.  Tegmina  linear,  about  as 
long  as  the  pronotum,  or  absent.  Hind  femora  extending  nearly  to 
(female)  or  a  little  beyond  (male)  the  tip  of  the  alxlomen,  the  superior 
margin  unarmed,  the  hind  tibiae  with  their  outer  edges  smooth,  the 
spines  similar  in  length  on  the  two  sides,  those  of  the  outer  series  nine 
to  ten  in  number;  first  and  third  tarsal  joints  equal,  the  second  less  than 
half  as  long  as  either.  Abdomen  indistinctly  carinate  throughout,  the 
extremity  scarcely  enlarged  in  the  nmle;  subgenital  plate  ampliate  at 
base,  short,  not  projecting  far  beyond  the  tip  of  the  snuill  sui)raanal 
plate,  and  in  i)articular  so  little  elevated  posteriorly  as  to  expose  the 
recumbent  pallium  more  or  less  to  a  i)osterior  view;  furcula  feeble; 
cerci  styliform;  infracercal  plates  highly  develoi)ed. 

In  general  appearance  the  species  <»f  this  genus  most  nearly  resendjle 
those  of  Gymnoacirtefes  Bruner,  Paradichroplus  Brunner,  and  Scopus 
Giglio  Tos.  The  distinctions  of  the  genus  from  tlie  iirst,  besides  its 
ampliate  subgenital  plate,  are  pointed  out  under  that  genus.  From 
Paradichroplus  it  differs  in  its  more  compressed  body,  the  more  taper- 
ing vertex,  the  slenderer  tegmina  (when  they  are  i)resent),  the  lack  of 
any  enlargement  of  the  tip  of  the  male  abdomen,  with  the  shorter  sub- 
genital plate,  the  ampliate  basal  margin  of  the  same,  the  posteriorly 
exposed  pallium,  and  the  wholly  simple  cerci.  From  Scoi)as,  which  I 
have  not  seen,  it  appears  to  differ  in  its  more  ])rominent  prosternal 
spine,  its  narrower  labrum,  more  declivent  face,  less  cylindrical  pro- 
notum, with  its  excised  posterior  margin,  besides  its  simple  cerci.  Its 
subcouical  head,  especially  in  the  female,  gives  it  a  peculiar  asx)ect. 

A.  sphenarioides  Scudder,  is  the  type. 

Three  species  occur  in  the  Southern  States  along  the  borders  of  the 
Gulf  of  Mexico,  and  may  be  separated  as  follows :

J5()(ly  green;  head  green;  eyes  narrower,  at  least  in  the  female,  than 
in  ^l.  sphenarioiiles,  more  closely  approximated  above,  and  the  fas- 
tiginni  in  advance  of  them  less  swollen.  Tliorax  with  sculpturing  simi- 
lar to  that  in  A.sphenarioides,  but  wholly  devoid  of  any  lateral  stripe  or 
with  feeblest  signs  of  the  same  in  the  female ;  in  the  male,  however,  there 
is  a  faint  pallid  stripe,  edged  feebly,  narrowly,  and  interrui)tedly 
beneath  with  very  dark  green.  Tegmina  wholly  wanting  in  both  sexes. 
Legs  as  in  the  other  species,  except  in  wanting  the  testaceous  color  on

subtriangular,  with  slightly  convex  sides,  tlie  apex  acutely  angulate, 
the  surface  tolerably  flat  except  that  the  lateral  margins  are  elevated 
on  the  basal  half,  the  extreme  tip  is  suddenly  raised  to  a  higher  level, 
and  the  median  basal  sulcus,  which  reaches  to  the  middle  of  the  plate, 
is  flanked  by  heavy  parallel  walls  which  unite  beyond  its  tip  and  extend 
nearly  to  the  apex  of  the  plate;  furcula  consisting  of  a  pair  of  minute, 
rounded,  divergent  lobes,  seated  upon  the  ridges  bounding  the  median 
sulcus  of  the  supraanal  i^late;  cerci  much  as  in  A.  ruforittata^  but  taper- 
ing a  little  more  rapidly  on  the  basal  than  on  the  apical  half;  infracercal 
plates  very  broad,  concave,  tapering,  entending  beyond  the  supraanal 
plate  by  their  slightly  thickened,  bluntly  pointed,  slightly  separated 
apices.

1.  Poepedetet  coralUnus  Sausaure,  Rev.  Maji.  Zool.,  1861.  p.  I.tH.  ^Icxico  temperata.  It  is  doubtful 
If  thia  Mexitaii  species,  unknowu  to  me,  belonjts  in  th*-  Melauopli:  it  seems  to  be  more  nearly  allied 
to  Dactylotuni. 

2.  Pezotettix /auriei  Bolivar,  Anal.  Soc.  Esp.  Hist.  Nat.,  XIX  (1890),  pp.  3J2-32:J.  This  ai)e4ie8  from 
Yeaao,  JaiKUi,  seems  to  be  a  Po<Usma.  but  it  is  descrilH-d  from  the  female  alone,  so  that  I  can  not 
pla»e  it  more  closely. 

3.  Caleoptenus  (»i<;I)yfapolim'at«« Thomas,  Bull.  U.S.  Geol.  Surv.  Terr.,  I,  Ist series.  No. 2(1874),  p. 68. 
I  am  unable  to  determine  this  soutliern  California  species,  and  am  tolerablv  contidentl  have  not  seen 
it :  for  in  this  case  there  is  apparently  anrticieut  in  tiie  descrij»tion  to  tix  the  species  when  si)ecimenH 
are  obtained.  It  has  been  thought  by  some  to  be  Oedaleonotus  enitvna  coUarin.  hut  that  is  scarcely 
possible. 

4.  Pezotettix  mexicana  Sausaure,  Rev.  Mag.  Zool.,  1861,  p.  160.  Mexico  teraperata.  From  the  descrip- 
tion it  is  impossible  to  detennine  which  of  the  many  Mexican  species  this  may  lie,  but  I  suspect  it 
may  prove  to  be  Melanoplun  atlanlx. 

5.  Pezotettix  mikado  Bolivar,  Ann.  Soc.  Esp.  Hist.  Nat.,  XIX  (1890),  p.  323.  Yesso,  Jajtan.  Likethe 
other  sjjecies  of  Bolivar,  No.  2,  this  is  describeil  from  the  female  only,  and  I  can  not  jilace  it.  It  is  pre- 
sumably a  I'odiama. 

6.  Caloptenus  repletiis  Walker,  Cat.  Derm. Salt.  Brit.  Mus.,  IT  {UIO)  pp.  678-679.  I  had  thought  this 
speciea  to  be  probably  Melanoplns  bilifuratus,  but  there  was  little  in  Walker's  description  whereon  to 
bnse  an  opinion.  Mr.  Samuel  Ilenshaw,  however,  kindly  compared  hiliturntus  with  the  apecimen.s 
placed  under  rcj>i«'<i(.*  in  the  British  Museum  and  found  them  «listin<t.  Walker  credited  it  to  'U. 
States"  and  "Vancouver's  Island,"  one  specimen  each,  but  Mr.  Uenshaw  found  iu>  specimens  from 
Taneouver,  bnt  two  males  and  a  female  from  "  North  Anu'rica,"  one  specimen  being  farther  labeled 
"Illinois."  The  two  males  weredilierent  species,  one  being  Melanoplus feuioratun,  theother  (Illinois) 
distinct,  but  allied  to  it  by  the  cerci,  though  with  short  tegmina  (probably  Milnnoplug  viola).  It  was 
further  doubtful  whether  the  female  belonged  witli  either  of  the  males.  Certainly,  then,  we  shall  be 
obliged  to  consign  Walker's  species  to  merited  oblivion.  Probably  no  one  of  these  specimens  is  one 
of  the  original  types. 

7.  Calliptanuit  tanguitieipes  Serville.  Rev.  Metb.  Orth.  (1831),  pp.  93-94  [Aerydinin  sangmneipea

opli.  If  De  Geer'a  Aeridimn  aeneo-oculatum  i.s  the  .same  >  his  figure  would  lead  its  to  presume  it  did
